Here we talk about the ins and out of sharpening. From beginner information to more advanced sharpening. Everything sharpening. My name is Scott Gunn. I have sharpened for over 30 years. Hopefully over a lifetime of sharpening I have picked up some information along the way that helps you. I have been teaching people to sharpen or help them troubleshoot issues over the internet for years. I have been asked for a longtime to do a KZread channel and share the information that I give them. So here we are. I’m just looking to help as many people as I can. Look for the tech tips. Tech tips are short videos giving quick technical tips so you don’t have to watch a longer video just to find that one tip that you have been searching for. We’re in the beginning stages and the videos are raw right now. My 13 year old daughter is my producer so to speak. We’re hoping to grow in this together. My goal is to provide something for sharpeners at all levels.

how often would i have to re-apply gunny juice to a leather strop?
@@frankjippy875 I reapply when the GJ isn’t cutting as fast as I want it to. I don’t apply as often as most people, but I also don’t do as many passes as most people
@@GunnysSharptalk do you just re apply it on top of the old compound?
@@frankjippy875 yes sir I do. Every so often I might clean the strop if I feel like too much compound and steel have built up. Then I have to apply too often. At that point I will clean the strop or use a new one
@@GunnysSharptalk thank you!!
How many square inches can a 10ml bottle cover ??
@@cmtwgrdk2748 it can vary drastically depending on the stropping material you are putting it on. Some materials soak up the liquid carrier faster than others. Generally a 10ml bottle goes a long way.
Thank you for the video
That looks more like a benchmade griptilian..
They both were Spyderco Gayle Bradly 2’s
@@GunnysSharptalkI know, was just saying it looks like one as I love the sheepsfoot blade shape. So much so that I have 5 Griptilians, 3 full sized, lol. It's been my work knife for 9 years. Only knife that came close to dethroning it was Spydercos manix 2.
@@seniorxj2931 Oh yeah the blade shape kinda does
Still watch this video from time to time.
Ok so as the micron number does down, the grit gets higher. It's crazy how hard it is to find this answer specifically
Micron is an actual measurement of particle size. It’s a micrometer. Grit is more along the lines of mesh size of the sifting screens
@@GunnysSharptalk so 1 micron would be the finest, and 6 micron would be more coarse then?
@@edcPatriot 1 micron is finer than 6 micron yes. So from coarsest to finest in Gunny Juice is 12, 9, 6, 3, 1, 0.5, 0.25 and 0.1 micron
@@GunnysSharptalk awesome thanks for the info 🔪👊

Was having a bear of a time finding this information in the wild. Thank you for putting it on your landing page. Took a while to come here but so glad I did!
After a 5000 grit or 6000 grit stone, what would be my progression with Gunny juice if I was trying to work on straight razors with strops? What juice makes sense after a 12,000 grit stone? Any help is very much appreciated!
Go with 1 micron after 5-6K and 0.5 after 12k
Nice Tip - Thank you
I own a few Mayabi birchwood and black knives. Getting ready to do some sharpening. What grit gunny juice would recommend for a mirror finish? PS I use a TSPro Kadet pro sharkpening system
I’m usually at a mirror by 3 or 1 micron. What’s your highest grit stone
@@GunnysSharptalk A 5000 grit shapton stone
@@mikesamolsky4719 you should be able to have a decent mirror from the 1 micron. As you go lower in micron size the depth and clarity of the mirror gets better. But the 1 micron I believe you will be happy with
@@GunnysSharptalk thank you very much
I have heard positive things about your stuff. I am a retired journeyman machinist so that is the basis of my experience with sharpening and finishing. Please do not take my comments as criticism. You come across as an energetic guy that believes in his product; with good reason. But you have got do a much better job on your videos demonstrating its value. The screen angle was awful and distracting throughout. Too much happened out of the view of your potential customers and the audience who will influence others. It’s all about networking you know. The camera looking over your shoulder showed you stropping and then you looking at the progress. Very little else. I hope you understand what I am trying to say. I also sincerely hope that you succeed in your venture. Don’t give up on all your hard work! Have someone help you set up the stage and watch your recording on some kind of monitor. Have someone who cares enough to be honestly objective and tell you the truth about it looks as you go. And if it is something you can’t be proud of, start over. That sounds harsh but it really is better than a video that makes you look bad. To wrap it up, I am 80 years old; I have seen a lot. I’m still working in my shop. I want to use your product. So hang in there! Don’t make the same mistakes that so many people cranking out lousy videos do. Most of them are pitiful. Spend more time time, effort and money on your videos. Right now this the one opportunity to directly talk to the ones that will buy from you (or someone else). All this is just the opinion of an old man who wishes you the very best.
So what micron size junny juice should I buy?
What’s your goals? Low grit edge or high polished edge? What’s the highest grit stone do you use?
@GunnysSharptalk I just bought the sharpal double-sided diamond sharpener, and I'm new to all this, but I want a sharp working knife and able to sharpen my wife's kitchen knifes. What would you recommend
@@GunnysSharptalk I use the KME, highest stone I use is the 1500 diamond, after that I go to spyderco fine, then spyderco uf, I strop with Kme cbn emulsion, 4 micron, 1.5 mics, then .5 mics which I'm not happy with, looking for something different then the cbn emulsions.
@@Reddirt_panda a 3 micron should deburr and leave a very nice edge for you
@@TonyRIKKI the 3 and 1 micron or 1 and 0.5 micron should get you where you want to be. It depends on how clean the edges look for you after the UF
Great video, I learned a good bit from this one. Never heard anyone explain things this way. Have a great day sir!!
Thank you, glad it helped
Hi gunny, where can we buy the gunny juice?
There’s a partial dealer list here us-aces.com/
I have a question if you dont mind. I just got a big delivery of gunny juice from 6 microns to 0.1. Really happy about that, but I was wonder what your opinion is for the best substrate or strop material is to use gunny juice on? Theres just so many choices and opinions.
I use Gunny Cloth and basswood with 3M micropore tape on it the most
Thank you again for these videos. I just ordered every micron Gunny Juice in 10ml to try out. I noticed from your videos as well as others that use Gunny Juice, the strop is always on a table & the blade being stropped on top. But, one video i seen, forgot who, used the Gunny Juice on a strop attached to a blank & stropped in a TSPROF Kadet Pro. They were stropping in the same way you would sharpen a blade. Is this way recommended at all? I have yet to see you stropp this way. Also, since the strop is facing down towards a blade locked in a sharpening device, would you lose product/ diamonds while stropping? Thank you again for your videos....
You shouldn’t lose product. There’s nothing wrong with stropping with a TSPROF. I am a freehand sharpener by nature. I started with stone in hand sharpening. So I have a better feel for stripping holding the strop. I can feel when more or less pressure is needed. Sometimes one side needs more work than the other. I can feel that. So for me I get better edges if I hand strop.
@GunnysSharptalk I appreciate you getting back to me on this. Thanks again for sharing your knowledge.
@@ericward9159 np. Happy to help
03/24/24 Thank you for making these videos. Im just getting started in the "sharpening world" & have learned a lot from you. I have a question about stropping on wood with the 3 micron tape. You mentioned using Bass with 3 micron & Ash with 1 micron. What about the other Gunny Juice such as 9, 6 & so on? Is there a science to the micron & type of wood strop or just personal preference? Thank you in advance...
Thank you I am glad the videos help. I use 3M micropore tape. It’s a surgical paper tape with holes that are only 2nm. So 1 micron and below I prefer either Gunny Cloth strops or basswood. I use the wood both with and without the tape. 3 works well on any stropping material. 6, 9 and 12 micron works great on leather
@GunnysSharptalk Thank you again, this is good info.
@@ericward9159 np happy to help. If you ever have questions you can always message me on FB messenger too. Under Scott Gunn
Some of the best advice I've heard yet.
Thank you 🙏
How long should you let it dry on a new nano cloth strop before using?
It really depends. It can take a few minutes to an hour or so. It’s a water based carrier so temperature and humidity factor into drying times
I have always heard that not removing the burr is why your knife feels sharp at first, then very quickly feels dull because the burr has rolled over. How is this any different from that? You're [lightly] cutting into something while still having a burr.
Lightly cutting into the wood helps to remove the burr instead of rolling it over
This is the PERFECT VIDEO for what I have going on with my manix 2. Its sharp as fuck but its wonky from factory
Thank you, I am glad that some of these videos are helpful.
Can I use Gunny Shines on my Poltava Premium Metallic CBN Stones? If so, how would you recommend I use it?
Absolutely! I use it to clean my stones with a couple drops and a Magic Eraser. I also use it instead of water when I sharpen. The stones don’t tend to load then
I love all the in depth info. For some reason I'm having a hard time finding granular information on this subject with other youtube videos
Because most do not know. Abrasives whether in stropping compounds, stones, sandpaper, belts etc. I would prefer the standard be a combination of micron size and abrasive concentration.
Awesome video. I learned a lot 😊
Thank you 🙏
Hi! Is there a reason you don't use the K03 expert rack and pinion riser on your K02? Thanks!
Look at newer videos. I do actually use the K03 riser. I started with the K02 then converted to the K03 when they came out with the conversion kit
@@GunnysSharptalk do you feel like it would be worth about 200 USD to upgrade to the new rack and pinion riser? Or is it just my FOMO acting up? Also, do you ever really need to have an angle higher than 30 dps?
They did this to prevent China from using s45vn steel.
Does practical sharpening still have a website?
Which side of a kangaroo leather strop would you recommend to use your product on?
The smooth side
@@GunnysSharptalk Thank you, sir. 👍
Have a question. My knives seem to get better and better as I progress through the stones, but when I get into the higher grits 2K+ and strop I usually lose apex sharpness and I’m not sure if that is my technique or if the steel doesn’t like the higher grit. Maybe I’m using too much pressure. That has to be the case with stropping. Using high grade leather or bass wood with gunny juice. Lot of variables and I haven’t quite figured it out yet. I should probably do more testing between progressions too. double digits on a Bess is really good for my skill level. 70-90. Think I’ve gotten a 40-50 once or twice and that doesn’t always translate to hair whittling either. Getting better and still confused. Ha!
You’re likely making too many passes or raising the angle slightly and over refining your apex. Sounds like you get great edges. And hair whittling has some technique to it also
knife bros are dumb asf man. it blows my mind how much dumb shit knife bros believe. its worse than a cult. and if you're wondering, by sharpening the edge with the correct abrasive thats finer than the smallest carbides in a given steel you increase the edge's toughness by marginal amount. this is because the so called "teeth" as microscopic as they may be, if they are large enough based on the grain and carbide size in the steel create areas where fractures are more likely to form . this isn't some edc bro nonsense. it's empirical fact. So that is the benefit of a correctly done mirror edge. it's less likely to chip.
Big fan, Great product. Hear it is in late January 2024 and I cannot find what I want through any vendor. Looking for 3 micron in the 30 ml size, Whats the problem?
3 micron is here my labels haven’t showed up yet. Hopefully tomorrow. Logistics kills me sometimes. I know we shipped a bunch of stuff last week, but I would have to get to my office to see what shipped.
And thank you for the support. I hope to have more products ready for Market by the end of the year
January is usually a very slow month. And December the factory closes most of the month. I am just getting some items I ordered at the beginning of December. Then we had a ton of orders come in at the end of December and January. Usually things are dead right now and they pick back up at the end of February or beginning of March until mid May. Then things die until Blade Show Atlanta. The summer slows down until mid August or early September. Generally September is my biggest month. The peak times are changing and becoming more random so I am trying to navigate the new trends. Unfortunately being a mom and pop show I can’t afford to sit on too much inventory at once. We’re continually restructuring things to be in a better position to be ready for the fluctuations in business. I have been hitting the automotive industry such as carwashes and detail shops to sell my Gunny Glow “The World’s First Smart Cleaner”. Here’s my website that covers product information and dealer list. It’s time to update the website and add dealers, but the ones one there usually order from me fairly regularly. Hopefully my labels are done before the weekend is out. Again I appreciate your support. As I restructure things I am slowly putting things in place to speed up the process and to stock more inventory
Great product, too bad that right now, late January 2024 I could not find what i wanted in the grit rating or size. What Happened??
The short answer is the factory was closed most of December. So product is just coming in from the end of November and beginning of December
On what kind of strop did you put the gunny juice? Leather/wood/nanocloth/?
Basswood and I used Gunny Cloth strops
Spyderco are excellent knives, just got my first one. Love this company, need me a pm2 as well. Have the manix in s30v with the g10 and it’s amazing.
I was wondering if you could shed some light on mono vs poly diamond. The guy who makes stroppy stuff(and some others) claims that poly doesn't have the same fracturing characteristics(or the other benefits poly is supposed to have) when talking about submicron particle sizes and stropping-level pressures. I've read the study he uses to substantiate that claim, and some other studies by the same author, as well as others, and quite frankly I have no idea what the right conclusion is. One study showed quite a difference between poly and mono even at 1 micron size. The only thought I have is that polycrystalline should still have the benefit of having more cutting edges even without fracturing. Do you have any opinions on this matter? Ken Schwartz also mentioned in his blog that monocrystalline has its benefits as well(talking specifically about a stropping compound), but I can't really figure out what those would be. Even in the context of diamond plates, most people talk about mono lasting longer, but I've found several threads talking about poly cutting for longer and better.
There are far more studies showing that poly has better finishing characteristics than mono crystalline diamonds, in metallographicpreparations. My products speak for themselves. Unlike some other companies, I have no need or desire to attack other companies. I will say that they obviously do not understand the science behind anything they’re doing. Just because they don’t understand the science doesn’t mean the science is incorrect. Diamond manufacturers explain this. So are the manufacturers incorrect? A certain maker of mono sprays and their followers are the only ones I know of saying mono is superior to poly. And 1 person trying to convince people of that. Honestly on hand strops there’s not enough pressure and heat that you will readily fracture either one. They will over time. Or using powered stropping or grinding. All the diamond manufacturers say pretty much the same thing. Mono crystalline diamonds can do a nice job on edges, but it’s not the same. It’s in no way superior. I have countless hours of my own testing. If I could make mono crystalline diamonds work as well as my poly formulas then I would change to mono. Mono is a third of the price poly are. I could have better profit margins using mono or half the concentration of my formula now. I would rather the highest quality product that I can provide. Here’s just one diamond manufacturer agreeing with me. www.superabrasivespowder.com/the-difference-between-polycrystalline-diamond-and-single-crystal.html
@@GunnysSharptalk Thank you for the information. I had some doubts about his reasoning already. He said specifically in his video that the grain size of pcd approaches that of the whole particle at smaller sizes like 1um, but as far as I know, polycrystalline diamond can have grain sizes in the single digit nm range, which is not at all close to 1um. I can only imagine that he read something about PCD used in machining which does have much larger grain sizes. I've tried to read a lot but there's only so much you can learn without being able to experiment yourself.
@@entropy1454 we can take PCD down to 0.008 micron. The issue he has is the way the diamonds are made, cleaned and filtered. So without using our proprietary process of creating and suspending the diamonds 1 micron could become the lowest limit. That’s because without our proprietary deionization of the diamonds you have agglomeration. That’s where the diamonds stick or clump together. That causes the abrasive to grow. Sometimes as large as 30 micron. We can guarantee that our diamonds are agglomerate free. Even at 0.008 micron. Some people don’t like that they can’t duplicate my process so they try to debunk the science with empty theories and emotion. Try my product side by side with any product you choose. If my product doesn’t out perform any of them then I will buy my product back and pay for the product that you prefer. And I will pay for you to ship it to me. I am not calling out any particular company because that’s not my style. I’m willing to do that because I made the best diamond stropping compound on the market. If that ever changes then it’s worth the cost on my end. Because that tells me I need to work on improving the formula
I've always felt the little thinigs are what refines talent & takes you to the next level. Thanks for sharing.

Sir thanks so much for your prompt response. Great Customer Service. I live in Houston and so I will call Best Sharpening Stones in Houston tomorrow to pace an order. But they only list 6 micro and do not list 1 micro. I will place an order for the 6 micro and will continue to hunt for the 1 micro

I wouldn’t use this machine to do that. High end beauty salon sheers are more complicated than regular scissors too
Great video. If you could only pick one would you go with a 3 micron or .5 micron for use on a magnacut blade?
Go with the 3
Thank you
I have the worksharp elite knife sharpening system. Do you think this technique would work with that system? It does great on my other blades but ive never sharpened a crk tanto and im a bit hesitant

Would be good to know what micron size suits what end purpose. Clearly the smaller the more refined, but to those on a budget, what is the best single size, or size progression for the money? Say for kitchen knives.
So you’re only looking for one micron size? I personally use the 0.5 micron most often as an all purpose. Most popular sizes are 6, 3, 1 and 0.5 micron. What’s the highest grit stone you’re using?
I’d like to know also. Im slowly broadening the number of stones I have, but currently I’m finishing anywhere between 600-1200 grit. Occasionally a little toothier but normally 6-12 for now.
@@jonathanbezjian4301then you can finish it off with a 6 micron. And if you have extra cash you can also get a 0.5 micron to polish it off.
@@pullingthestrings5233 hey I appreciate it! Funny enough, after I left that comment, I went and ordered some Gunny Juice and accidentally ordered the .5, then returned it and bought the 6 haha! But I’ll probably purchase the .5 again soon. Thanks again, I appreciate the input!
