Sharpening Wheel For Razor Sharp Blades! MDF 

Now, I'm a lazy prick, so if I can get max results with min effort, i'll try it. I needed something, since I suck on a whetstone. So I bought a Lansky. That was good. Finally, I could get a shaving sharp edge, but I wasn't consistent and still needed to spend considerable time doing it. Anyways, found a 20 mm thick piece of plywood today and gave this a go. Holy crap! I shit you not.....3 kitchen knives to scary sharp in 90 seconds. On my Lansky, that would have taken 30 mins and not as sharp.....not even close. I love trying lots of youtube tips and tricks and some are ok, some suck, but this has got to be up there with the best I've ever come across. Thanks for sharing.....made my day!

This is incredible dude! Totally gonna go find some old motor to strap some MDF to now!

I can't believe that worked! I will do a mdf wheel on the lathe and give it a try! Thanks for the idea 👍🏼

Absolutely one of the best videos ive seen demonstrating this. Great work !

A sharp edge is often described as "Two perfect surfaces meeting together" and polishing them is a very good way to get close to that concept. Great project!

Back when this process was new, the wheel was made of plywood and the compound was Silverline Fine White. I ordered the compound about a decade ago and plan to actually make this wheel someday. It's amazing how time passes.

Amazing! Bro…you successfully just brought every stone and sharpening system down single handedly! I so wish I could have this, and because of how easy it is to make, I CAN! Thank you!

Damn yet another of your projects going straight onto my to do list! Well done as always!

Been using the compressed cardboard wheels similar to this for years. I run them backwards on a grinder motor so the rotation is moving away from the edge just as you do. There may be a bit more heat with MDF due to a higher friction coefficient, so a lighter touch may be required. The system comes with two wheels, one for sharpening with 300 grit powdered carbide glued on the wheel face. The other is plain for stropping with compound. I now wear a faceshield due to having a 14" Khukuri thrown into my face just below my nose. Luckily it was the spine that stuck me and not the edge. Still had to get stitches and clean underwear. I also run a foot pedal switch.

Knife building friend of mine showed me how to do that with a wheel made out of chip board a long time ago. Never considered MDF . Thanks for sharing.

I am in need of this. I will be making one of these this week. Great vid. I cannot wait to try this out.

that's a great idea thanks for sharing. I found that a buffing wheel is brilliant for restoring or finishing a cutting edge.

quick simple and obviously effective, amazing job

Your MDF wheel is a marvelous idea. It works well and gives a perfect burr to my knives. What i did in my setup is i use a grinder with variable speed to make it more precise. Also i polish on the back so the wheel spins upward. In case my knife is caught in the wheel, it just fly upwards and away from me. Thank you so much for sharing.

can't believe how well this works!!!😃😃👍👍

I’m always impressed at peoples building abilities ...... thanks for encouraging me to try something new for myself!

I like your idea, the way you used a pre drilled peace to make a perfectly vertical hole on the disc

Great video! I'm going to have to make one of these!

Sir, EXCELLENT and simple. Thank you Sir, for sharing this idea with us. Oscar

Awesome project Brother I need that! haha

great project my friend I like that second knife the best though it's a classic. By the way I still haven't got a sticker from you just to update you.

Awesome Truly Awesome, Cant wait to set this up in my shed, Thanks for sharing. Baz (uk).

i've seen several knife sharpening builds this is by far the simplest i will have to try thankyou for sharing

YES! Those wheels work so great!

Hi, I really liked your video, help me. I sharpen hairdressing scissors, would you have to use stone first to make a perfect edge? If so, would emery stone have to be used?

First Because of the bell button man AWESOME AS ALWAYS

Cool man, never seen the details of this before, add that to the project list. You fucking rock bro!

this video is so damn satisfying! I'm a huge knife freak, and.. yo! this video put me in a good ass mood!! great video

This is so darn cool! I never thought something like this could get it sharper than just stropping! I definitely gonna see how i can make one of these. Great work, that next video looks so cool! I almost don't wanna ask because it'll spoil the supprise! lol Cheers! :)

im totally doing this!

what a useful, helpful, valuable, practical tip!

ottimo!!

Sweet! That was great! 👌👍 Thanks for sharing!

Ideia grandiosa parabéns amigo valeu por compartilhar.

That's interesting! High speed can polish and sharp even using such soft materials :)

In my feed had to watch I think I'm hooked I think it's the music are you doing subliminal, LOL good vid

Hey. Thank you for the video. please tell me what you rubbed the disk for sharpening knives

Yep! What Mike said! I'm building one soon. I spend an hour on wood chisels and blades for planes and they're sharp but poor. Wit the help of a hammer I can get a jagged cut through paper(LOL). This will put me back on the job where the tools are 90% of the craft . Cheers Mr.. Top effort thanks.

Nice work!

This is it! Old idea that works better than All the fancy sharpeners and beats them in speed and price.

Awesome

I'm curious about the useful life of this type of wheel. What has been your experience? And an unrelated question: how do you think the Maguire's buffing and polishing compounds would work to produce a dazzling mirror finish?

I've seen good MDF sharpener builds but that portable lathe/tool rest device is brilliant! Please make a video of that!

That's freakin genius!!!!!

The best so far, Thanks for sharing. Have a great day.

Cool, I made a video about this for the wood lathe and it works awesome. Lots of knife nerd criticism though!

Awesome... it works like magic,. and after watching this video I have to make one to sharpen my knives ;-) I have just subscribed!

Great job,and you are very skillfull in holding the knife at the correct angle :-) liked!

Excellent video and process. Thank you for sharing.

Great Vídeo. What kind of compound is that you are using? Thanks

Thanks for a great video idea. Do you think it would work with plywood instead of MDF ?

I was considering buying a set of expensive Japanese whetstones but now I you came up with this.... Wow!

This is brilliant. I use plywood wheels to polish jade and other stone - pulled fibers kill them after awhile. Next time I'm trying MDF - the stuff is hard and UNIFORM - what a great idea!

Where your ideas come from, wonderful

can you tell me where to buy your "fine polishing compound"? I only found compound for plastic or acrylic not for steel! Thanks

Great idea I have a spare 6 in grinder I will convert over to this now.

Ciao, ottimo video. Non ho capito cosa usi da mettere sul disco prima della molatura

Is it as good as a belt grinder? Does the edge get dull fast?

So, you've got the polishing compound directly on the mdf?

Beautiful man do you think a semi perfect circle is achievable without a router? I pretty much only have hand saws at my disposal. I've been wanting to make one of these for a while but didn't feel like it was doable with my tools.

this is great man thanks for sharing

Do someone remember when I made this "tool rest" 1:52 ? :)

Very cool! Will have to try that myself. Any issues with burr you have to deal with? Did you do any stropping afterwards? I use a lot of different ways to sharpen knives but im always looking for a better or faster way.

Hello Black Beard! I have a few cuestions on same thing... At what RPM has to go the motor? Is that a very important thing? I mean, i have a electric grass cutter motor (a small one) but it has high revolutions... more power instead speed or a mix of power with speed? (like 1hp motor) THANKS!!! GREAT GREAT VIDEO!

One of the most helpful videos I've seen and no talking 👍👍 awesome 👌👌

Super! What is the paste you put on the wheel

Sir, What is exactly that fine polishing compound you use?

Great video,I have also seen sharping wheel's made from dance cardboard, or laminated leather!

Walter Sorrel did the same thing. Just wonder if the blade should be sharpened on a stone prior to the MDF-wheel. Which paste do you apply?

Great idea 👍 I didn't expect wood to make so good job

Thats on my to do list. You made it look too easy. Well done.

I thought you were gonna use the melamine side like a sanding wheel. That makes sense though! MDF is like an extremely fine polisher. Cool idea

I jurst made one,and it works wonderful!!

What do you apply onto the wheel before sharpening?

Does this method simply polish and deburr the existing bevel,edge or is it making a new edge? I'd try it because I dont buy expensive cutlery.

Heh love the USSR vice! Is that a brand name, or is it an "in Soviet Russia, vice clamps with you" job?

What substance have you applied over the wheel ? Please let me know the chemical name of that. On screen it shows as"Fine polishing compound".

I made this, works great.

I found a guy on e-bay (in Germany) selling 22mm x 13 cm (about 5" dia) disks for peanuts so I bought a couple. Do you think they will be too small (fast)? I will have to figure out how to drill the hole exactly in the middle, but that isn't rocket science. I also ordered a green fine polishing compound stick. Is there any disadvantage of working with the wheel turning toward one rather than turning the motor around? I would work from the side anyway, not from the front. Thanks for the useful idea.

simple but super effective and cheap!👍🏻

Nice project, thanks for sharing, but I have a doubt, what is this that you put on the edge of the MDF?

what's the compound your putting on the wheel ? ?

That looks like a concave grind. I do convex on my blades. I did like the trick on the drilling the holes with a hand drill.

Simply explained and simple to do. Thanks

This video was posted 4 years ago. How long does this wheel last and with how much use? Is there anything to the blue colored layer?

What is that lubricant you're putting on the wheel?

love you and your ideas

Great idea...looks like it works fantastic and I need this! Can you tell me what exactly is MDF ? I take its just a 3/4 in piece pf plywood or? Thanks alot man...appreciate it!

Perfect! What exactly is this polishing compound you apply ?

Thanks for the quick reply! Great videos Subscribed .

Hello, I don't see anymore this tool in your videos what do you use now and why ? Thanks !!

Does the high speed of the wheel not induce too much heat?

What kind of polishing compound is that,does it have name?And where can be bought,please posted.

How well would it work if you wrapped a strip of leather around a wheel like that? Would that maybe hold the compound better?

Any danger of messing up the temper along the edge due to heat? That's why I always thought using a wet/ or oil stone was best... Or a slow turning wet wheel...

With what did you rub in the surface of the wheel before sharpening the knife?

Excellent video and tutorial, thanks!

Well I'm impressed!

Wont this heat the edge to much? To much heat in a very thin edge will mess the hardness up

I absolutely LOVE this. I'm a fish cutter. I wish I could get my knives that sharp.
