Life long joiner here, 50yrs, a multi tool operates like no other tool, oscillation, used in the surgical trade for years and only became available to us plebs a few decades ago, well done Robin again.

I made one of these with a pack of mini grinder blades and a m10 nut & bolt & washers. They cut plaster board brilliantly once sharp.

I sharpen mine with a small, old school saw file. Got to sharpen while the teeth are still defined though otherwise it takes too long. A quick tickle up with a saw file makes a blade last 3-4 times longer though. Files are cheap too.

Where are you getting cheap files from? I need some 4" double extra slim files for a saw I want to sharpen here.

Brilliant for rough work and plasterboard,wear it down and re sharpen and save your good blades for finish work

Decent review Robin. Not sure I’d spend £70 on this myself especially with some of the smart multipack prices but like you mentioned; now you own it, it could get you out of jail one day.

Yes Sam thats how I am looking at it!!

You will find the teeth are hardened, in the heat treatment process. The rest of the blade is toughened only. As you grind the teeth down you remove the hardened steel and get into the softer region

I have a pile of these blades that I have yet to bin bc I held out hope that a contraption like this might well be the ticket. Sadly, it seems there is no substitute for new blade. Thanks for doing the legwork Robin. You are a gentleman and a scholar.

👍 nice tool better than nothing, earplugs is a must for this tool

Just need a saw file, a triangular file. 1- 3 rubs per tooth. that tool is just cutting square battlements. But it clearly works on the blade set that suits that tool. mainly wood blades. Do a video using a saw file on the wood and metal blades as a comparison. I wonder what the machine cutter looks like that makes these blades in the factory?

Thank you Robin.

Have you seen the tigers teeth blade sharpener? Nifty piece of kit, worth a look. Great vids Robin.

Yes the tigers teeth sharpener, although more expensive is great for sharpening other things too like drills, and circular saw blades etc on the job site. Well worth the money.

Fantastic, what with fathers day being just around the corner, I will be able to put it with the 'Gator' one size fits all socket, the magnetic tool holder wrist band, the combined tape measure pen and the all in one firemans axe and fondue set.

For broken multitool blades you can get a good raw cut using a grinder with a metal cutting blade. You could get a finer cut too if you took your time and a little more care.

Interesting video, might be handy if you were on your last blade and wanted to get to the end of the day, not sure if I’d use it routinely! I’ve tried a few different starlock blades (didn’t know these were more expensive when I bought the tool!) and found Hilti blades to be the best, last much longer than Bosch or Milwaukee. Best advice for blade longevity though is don’t push them too hard, run the tool on a slow setting so it can clear the sawdust and try to always use the right blade. Proper hardwood blades work far better in hardwood than a regular multi material.

Great vid yet again rob! Interesting! You got me thinking, buy or not ! 😂 I’ll wait until you put yours in production!! RC MULTI TOOL BLADES ASSORTED PACK OF 5 😂 Well done mate .

Declan Doolan happy to see robin crevitt about construction 🚧 industry

I must say I recently bought a ‘Bosch expert carbide blade’ for metal and was seriously impressed. I cut - accidentally - a piece of timber with said blade and it wasn’t great thus if it’s metal embedded in timber best to use a wood/metal blade, but if you’re knowingly cutting metal only I cannot recommend it highly enough. Reasonably priced at £15. Will be purchasing a fein one when it’s time to replace, see if it’s any better or longer lasting. So far with the Bosch I’ve cut about 6 Reisser screws and a few nails and still as good as new.

probably end up being a worthwhile addition in the end then. ive binned loads of these blades once theyve touched plasterboard theyre absolutely toast may even be something where the companies who sharpen circ saw blades could offer a better service. i get my festool blades sharpened quite regularly. normally 5 or 6 blades freshened up for the cost of 1 new blade.

A 4" grinder with either a diamond disc or thin metal cutting carbide disc does the job, only for cutting wood or plastic

The blades for multi-tools are the ink cartridges of the printer world. There is no alternative to them so they are way over-priced. I've been using small files to sharpen them, does the job. Thanks for sharing.

Dremel discs with washers between does the same thing for a tenner or even your old angle grinder discs

I'd be interested in whether tungsten carbide multitool blades are worth the extra expense. Project Farm did some testing. I think you need to price in blade cost for into your work if you anticipate a lot of use. Is there a professional resharpening service that will both do curved blade and re heat treat them?

Tell nick bundy he'd love this tool.

Those tool are also heat treated by using it like that you remove the treating making it soft and softer for next cut if your going to do that run it for a few seconds then put in water to ,keep cool

A good needle file set is what I use

Honestly you can just run a metal grinder disc into them and freestyle some ragded teeth and theyll cut ok. Also surely you need to clamp the blade in a vice and hold it at more of a 90degree to the sharpening tool.

That is true I have done that myself but... if I did that on KZread I would be crucified by comments about danger!!

I destroyed one of my cutters removing a sill on my garage I was replacing, ended up using a hacksaw to get through the nails😂😂 Maybe OK for a tradesman but for the average DIYourselfer I wouldn't bother unless you use them constantly, good demo.

Fairly sure the good blades are formed , tempered ,then ground , this device will use abrasion to form through the hardened steel alloy , this will leave the raw un tempered steel alloy , can’t see them lasting long , but as ever enjoyed the presentation . Love my HILTI too. I have a tiny 12v Milwaukee trim wheel ( Dewalt just copied it ) they go to 20,00 rpm & use 76 x 1.0 mm wheels easy job to mount a few of these on a mandrel and cut the finer teeth , again I think the loss of the tempering would effect the longevity .

Best tip with multi tools is to put the blade in at 90deg to the body and not end on. I was surprised at the improvement in usability and cutting performance this way.

Don’t know why but this video has me in stitches 6:53

Keep the multitool blade as close to 90 degrees to the sharpener.

Looks like a Temu special that one

I think a file with a triangular profile might me almost and quick and do a better job.

Yes but you need to use a diamond file on hardened teeth

got the cheap blades when i bought my multi tool. absolute junk, then tried an expensive diablo blade and it was a new tool. sadly they cost a fortune. might try some filing to get some life out of the blades. cheers rob

Could you please let me know what brand the safety glasses you use are, couldn't see them in your Amazon store 😀

Ebay has 66mm wide sharpeners for wider blades. They cost about 50 quid. If you can double the life of blades for wood and plastic, it could pay for itself pretty fast. Maybe small teeth would be a challenge.

I have a set of small files to sharpen mine takes 5 minutes.

Use a file like I do for my ordinary saws

tried tungsten carbide grit or teeth blades?

Isn't it only the tip of the blade that they harden to save costs, so little point in re-cutting as you will end up in softer metal?

Robin, make a jig !

A stamp guillotine to bite a new end would work better but I guess it would have to be fairly heavy duty. Personally I just but the bulk cheapo Chinese ones. They don’t last as long but they’re good new and only a quid each and so it makes more sense.

@ukconstruction

Yep I mentioned the fact you can get cheap blades in the video

From what I can see the blades are induction hardened like a jet cut saw. Once you've ground away the hardened zone the blade is finished. Jet cut saws are virtually throw away items and often cost less then a single multi tool blade. They can never be set and sharpened like the traditional saws, so what can you expect from multitool blades.

As you say, just a threaded rod with some washers and cutting disks. If you got some thinner washers and disks, you could set your own pitch. On a rainy day, stick it the pillar drill in the workshop, spend the morning rescuing blades!

NOOICE!

If ya gonna try sharpen them you probably gone be doing it for one job your currently doing an can’t be bothered getting a new one so maybe just get a little diamond file preferably the triangular one should sort it much better and probably a few quid for the file

This device doesn't seem well thought through at all given its limited width. @thetallcarpenter had a good tip for cutting down old handsaw blades and welding the pieces onto the bases of old multi tool blades. Also using a fine angle grinder disc to make new rough teeth works well enough. Both decent options for rough-medium finish work in wood or plasterboard.

There are two systems out that would work on metal-blades as they grind real teeth. Tiger teeth and schärfkopf. But they are getting really expensive...

Can't wait til Temu produce them for £5

All the metal blades, maybe you can sharpen them up to the rough blade, and then save them for rough wood only, and In future just buy new metal blades, knowing they will eventually become rough wood blades later on maybe. At least they still have a purpose rather than just throwing them.

Sharpening saw blades is a bit of a chore.

Try 1 mm slitting discs

I just buy the cheap ones off eBay 100 blades for £30 a couple of cuts throw it over my shoulder not bothered 30p a blade!

A three square file works for me

I'm not convinced at all by it. I must admit I never run my multi tool at full speed. So if I need to go through a nail I slow the spoed down to 1 or 2 then for timber I mostly cut at 3 or 4 and it's very rare I go to full speed I find the cutters last a lot longer as I haven't over heated them .

The years of proper experience shared is outstanding, also love Hilti tools, just swapping a lot of my 22V to the Nuron platform, the SID-6-22 is a monster, amazing kit, unparalleled support. Actually heat is a bonus on light tool steel, burn the hell out of it, get it blue and quench it in oil, better than the induction hardening they do on most mud range oscillating blades. The pitch being wider is probably their tactic to make a blade “feel” sharper
