I own Japanese water stones, an Edge Pro Apex, and a Work Sharp. I think that your assessment of all of these systems is exactly sport-on, and you've done a great job of summarizing the positives and negatives of each of these systems. Thank you for providing such a detailed and balanced comparison of the different systems.

I've been using the Work Sharp system for a couple of years now and I've never found an easier or more effective system. You can round off your tips if you're not careful, but you get used to it rather quickly and, once you get the muscle memory down, you'll never have that problem again.

Great video thanks. The greatest thing I can take away from this video is the knowledge that there isn't a complete sharpening system. I am absolutely amazed that in this day and age, you can't get a simple and fairly inexpensive piece of kit that is easy to use, quick to set-up, quick to give excellent results, cheap consumables, repeatable and leaves a razor sharp mirror finish.

Haha I also have 3 of the Ken Onion Worksharps, haha. I use Tormek T8 and Worksharp as part of my sharpening business and you can sharpen almost anything between the two. Both great products!

@Commie Hunter All belt grinding tasks a wheel can't necessarily do. Fixing heels, rebuilding tips and a bunch of other things the Tormek could probably do, but not as efficiently imo. You might not benefit from one, but I user them both for different things

Thank you for the real world and honest look at these systems.

FOR ANYONE LOOKING, I recommend going with a Ruixin rx-008 sharpener system for $50. It has a clamp to hold the knife so you don't have to with your other hand, and the stones are decent enough. I would recommend it highly over the edge pro and it fits the higher quality edge pro stones or any other stones designed for it.

I don't. The angle on both sides on the clamp is different. It won't fit smaller knives because the clamp is too wide. And the angle adjustement rod and clamp is badly designed.

First class comparison - thoughtfully presented in including all the practical considerations, and clear and well-articulated. Thank You very much.

I'm really pleased with this! It works like a charm kzread.infoUgkxDcr-y2Pf6xdnrFHrSP7dl9kpKaCozcSQ Takes less time than my old electric sharpener because it can take more off the knife faster, and then it smooths out nicely with the finer grit polisher. I don't know how long it will last before the grit wears away, but I wouldn't mind having to replace it every once in a while.

Hi Nick, informative video. I had a carving instructor that said he tried water stones and they didn't work, then he tried oil stones and they didn't work, went to ceramic stones and they didn't work, tried diamond stones and they didn't work.....Then he learned "how" to sharpen and found all those systems worked well.

I bought a t4. And it wasn't long before I sold it, it's slow, requires a lot of maintenance, and I wasn't super impressed with the edges I was getting. I also have the the worksharp KO with blade grinder attachment. What can I say, from the start, this thing agreed with me. It's my go to machine. I pretty well do everything I get on this, except for specialty work, in which case I use a KME. So like you, I recommend the worksharp KO with blade grinder. Peace.

Thanks for this video. Much superior to most. About the WorkSharp system....I am typical homeowner guy, not commercial. A couple of unmentioned benefits: #1 Belt sharpening produces a convex edge which lasts longer in-use. #2 WorkSharp also offers diamond-grit belts that allow me to maintain my otherwise-unsharpenable ceramic blades. The unit is easy to understand and use properly. Various grits allow fineness of edge to whatever degree you choose including leather strop at the end if you want. My resharpened edges are equivelant or better than factory, last longer and are accomplished within minutes per-blade.

Thank you! Great Vid. 🇦🇺

Thank you! Apex was great to see!

I have two Tormek T-8 systems. One is for heavy work and the other one has the Japanese waterstone on it all the time. This to me is the best option for as there is no heat involved and there is no dust from sharpening. All of the shaving are contained in the water tray. A bit of an investment at first but well worth the money.

Interesting that you recommend the Work Sharp system. Here in New Zealand we have the Scary Sharp NZ product that us very similar to the Work Sharp. I pleased to say that I own one of these and its ability to hone a knife is outstanding. Nice vid - thanks for sharing.

I'd try for a sharp knife...

Ive had my Tormek since the 90s. There are way more attachments than you mentioned. It's an excellent way to sharpen my turning tools, including my gouges. ..of course, it takes another jig. They also have very fine whet stones for it, as well as a jig for sharpening drill bits. Its a very versatile machine. I agree that it's an expensive machine. I think the one like you have is actually a smaller diameter than the older ones which makes a more hollow grind.. that's the big downside for me. Thanks for showing your technique for using that lapping work sharp stand. I have a similar one that i had to rebuild to make it sturdy and actually clamp down on my knives. I never thought to use the clamp as a guide and just hold my knives in place like you did. I'll try it like that next time.. thanks for the tip

I have the Ken Onion Work Sharp (with Blade Grinding Attachment). I love it. I can easily take a knife from dull to shaving sharp in a hurry and get 5 packs of belts for 20bux. If the guys at work want their knife sharpened, thats what it goes on. I also have an Edge Pro Apex. THAT is for my own knives. The Apex creates thise edges that no1 else has 😎

The Tormek T8 comes with everything to sharpen knives, scissors, axes, chisels, wood planes blades. You neglected the wheel on that T4 why it is hopping. It needs trued up and comes in most kits other than just the bare grinder. Plus I use the diamond wheel. I Am a professional bladesmith. I go from my 2x72 KMG-TX , then by hand on oil stones. Strop Might use my Tormek The wicked sharp is another great option not mentioned.

If I was going to do it for a living I think I would buy a combo like both the Formal and the Edge pro. The Tormak is also very good for chisels etc in a woodshop. Besides, the Wicked Edge is VERY cost prohibitive if you want all of the best stones etc.

I’m just starting out as a knife collector and I bought a Work Sharp Ken Onion 2nd generation. I haven’t used it yet but am kinda concerned about convex edges… My intention was to get a straight edge and intend to do most of my pocket knives around 17-18 degrees per side.. I’m going to use a junk knife to practice with… IE: sharpen/blunt/ resharpen…. till I get somewhat proficient at it.. I don’t want to risk ruining my blades…

Great comprehensive review!! I’m an OCD, bi-polar maniac who has a renewed obsession to knives and sharpening. I have an Edge Pro, grinder w paper wheels, various stones and leather strops. I achieved a few mirror finishes on the Edge Pro w very expensive after-market stones, and literally never even removed the grinder from its box. My focus is renewed on the Edge Pro for custom knives, and finally gave up on my obsession w purchasing the water wheels. I can utilize the bench grinder for mower blades, axes, etc as a side business to legally compensate my disability benefits while keeping my mind focused. Appreciate the video!! Best sharpening review I’ve seen!!

Can you put compound on the Ken Onion belts when they wear down?

I have the work sharp and while for the money it’s ok to keep your knives at a decent working edge, I wish there was a platen behind the belt for some contact.

Very nice and informative video! But I have to nitpick about terminology; they're not "wet stones" but whetstones which comes from the verb "to whet" = to sharpen with grinding strokes.

I hate a dull knife ! I found going to someones home where they have me help in the kitchen and the knife is dull I have been caught in a pinch using the exposed ceramic on the bottom of a cup or bowl to bring back some sort of cutting edge on a knife. People just don't know how important a sharp blade is in the home. Thank you for an HONEST review on the different systems. I have gone thru a few systems after looking at many, many videos that will not tell you the real truth on problems with each system. I don't see it mentioned in videos when using belt sanders your knife will wear fast. With a wet stone it takes a lot and I mean a lot of practice to get a sharp strong edge. And not to mention the maintenance for the stone to keep it flat. You do mention the down side for the units which is very important when deciding a system that will be good for you. And not to mention the cost for belts . LOL LOL I started out many years ago with the wet stones going up to 6k . I know it's me that couldn't achieve a good sharp edge and not the stones. I found the HF 1 x 30 which gave me a great sharp edge but was waisting the knife material . The HF unit is way too fast so the knife must be cooled with water often along with very light pressure against the belt. The strops turning too fast also will round out the sharpened knife edge so you must re edge the blade. Then a few months ago I just started using the tspro unit from Russia . I really like it . along with a foot long strop with green paste on one side and white paste on the other. The blades stay sharp and have a mirror finish also don't remove a lot of material from the blade. I am using the strop a lot after using the knife. I find the time while watching the tv .

He said he sharpened a lot of Kvives so here is a little tip for extreme change in result: use a TT-50 and make your stone round. I´ve never seen a stone this bad.

here is a thought for you HF Survival School. You like the belt grinder system. Im wont say anything against your preference however seeing you wear the belt so fast have you consider the price of larger sand paper sheets. Maybe buy bulk from manufacture make further deal. Then just matter of trimming to size and glue to old used belt.

Very helpful. I am a novice knife maker, but struggle with getting a good edge on the knives I make. Based on your info provided, it sounds as if the Edge Pro might be a good choice. Would you agree? Tormek is more than I want to spend, and frankly too fiddly. I would be afraid of the Ken Onion scratching a new knife. Any opinion on the Lansky systems? Thanks

I mean the term best sharpener is going to be all depending on the stipulations of what the goal is. Do you want a sharp knife or do you want a wicked sharp knife. By all means almost any sharpener will make a knife (sharp). The worksharp is a great choice for anyone you can make a knife sharp or use a little talent and skill and make it wicked sharp pretty easily. The stones and kits that use stones take more skill more time and get better results but it's at the cost of alot more time and possibly money too. I recently got the Ken onion and I love it, got a pack of cheap belts that are not worksharp brand but work very well. I have no issue getting a razor edge even on a badly damaged knife in comparison to my last kit the time difference is what's the biggest deal to me

I sharpen my knives with an Arkansas stone ,diamond plates and a suede split strop all by hand all by eye and feel so fast so easy you just have to develop the skill and then its like riding a bike ,you never forget !

For the workshop I use it to remove chipping but not to hone or create and edge bc if you notice the belt sinks in giving you an inaccurate angle/edge. You'll notice it when you cut paper and the paper tends to slice in an uncontrollable angle vs straight through. You should use something with more precision after.

Spyderco sharpmaker ($100) is good for maintenance, Lansky ($40) is good for consistent or reprofiling edges, Japanese water stone ($100) for detail and a leather strop drill attachment ($25) with compound ($20) for mirror. If I get nicks or buy a new knife with secondary bevel, I use a 4” sanding belt ($120) with 80 or 120grit to get started. Burr first, then move to the more fine sanding. I can’t stand the weak concave edge of a bench grinder.

A very good video to pinpoint the serious pros and cons of each one. The Tormek has some crazy wobble on both wheels, if this is only after 50 sharpening jobs, it is just bad. The Work Sharp KO seems to work so well for 99% of the uses. The only thing I don't like is that the "push" grinding function becomes a "pull" grinding when you flip sides. The Work Sharp with the blade sharpening attachement avoids that problem, but then you better have some steady hands for accurate sharpening. The Edge Pro seems so well designed, for sure one of the top choices for a manual sharpening method.

Yeah I reckon the Tormek main wheel is running eccentric; surely it wouldn't come from the factory like that. Perhaps the hole in the wheel is too big for the driving shaft. Whatever the cause, it needs dressing down with a diamond point - unlikely you can do that with the speed setting on this machine

Dobar video !

I have all the products you demonstrated. I used the work sharp with the knife grinder attachment almost exclusively. I found belts on line that are reasonable 18 belts for $11 American. I also found 5000 grit belts that when the get worn out I use as stropping belts with diamond paste that is 200,000 grit. Under a magnifying glass ALL scratched are gone. Also if you move the top two wheel closer together, Allen wrench required, you can get a let’s con-vexed edge. So still stronger edge and sharper. I’ve been using my Ken Onion w/ knife grinding attachment for 2 or more years, at full blast. Well over 300 hours. One in awhile I clean it out what little there is to clean. Especially since I use white, green stropping compound which get all over the place as well as the diamond paste mentioned earlier. I like the Tormek but the wheels are always slightly out of round and square around the edge. There is maintenance to be done always. Keeping clean water in the reservoir. Cleaning the wheel and other things. It works GREAT. The Edge Pro is also incredible. It versatility of the work sharp with the attachment I can sharpen axes, loppers, knives of any length, hatchets, and so on. Wow that was a long post! Loved your video and like you said, it all about what you’re comfortable with. I have Hugh end Japanese water stone from 300 to 15,000 grit along with diamond stones for when I’m in a hurry. If I’m doing a chefs Yanagiba, I only use the water stone. Right product for the right job. Keep the videos coming. I found it very accurate!

@@gallimore444 good question! Any belt sharpener will give you a bulged profile as in the edge isn’t completely flat because of the flex of the belt. This edge is great for a two sided edge but for a single edge with a secondary bevel and the concaved back I find flat water stones better for me. You can use the Ken Onion w/knife grinder attachment I just prefer not to with Yanagibas It would be like sharpening a chisel on that gear. It could work but why. The flats are as important as the edge. With a regular double sided edge the belts leave more mass behind the apex for, hypothetically,, a longer lasting edge. I hope that helps
