Here is a reference for those of you who use japanese water stones on your kitchen knives or razors. in western sandpaper: 1200 grit = 3.8 microns. in japanese water stones: 2000 grit = 6 microns 4000 grit = 3 microns For a more practical compariaon: a 1200 grit belt will provide a grind similar to the Naniwa Green Brick of Joy, which many sushi shokunin(myself included) use to touch up their knives between shifts. The feel of the polish will be different, but the toothless of the edge will be in the same range. Therefore this belt system will give you a good, toothy, 'full shift' edge. This level would be acceptable for more hard use blades like Deba, Honetsuki, Sushikiri, unagikiri, hamokiri, etc. Following this up with a polishing stone or two above 5000 grit would give you an edge suitable for blades such as yanagi, takobiki, usuba, etc. There are times though, when you want a more toothy edge on these thin, slicing knives. For example; on extremely fatty or oily fish, a highly(12000+) polished edge is actually too smooth and can lead to less ideal cuts than an edge in the 3-6000 range would. I have a yanagiba that i only sharpen up to the Green Brick of Joy level for precisely such occasions. In theory, this system and a tormek(with the replacement japanese stone wheel) would produce comparable end results. As to the potential time savings, I will have to wait until I build a Revolution grinder for my shop and try it for myself. For what it's worth; the folks over at Japanese Knife Imports use a combination of 2x72's, small(horizontal) kaiten toishi's, and both natural and artificial water stones to do repairs and put final edges on blades for customers. I hope that helped.

Hi Brian, I really like your grinder design and my own build is highly influenced by your design but in a bolted version. As I saw this video I directly started to look for scrap pieces and did't found long enough parts. But I found a even more simple solution. Placing the flat platten in the lower tube and the work rest in the upper one. Clamping an angle iron on the workrest and moving the workrest up as far as needed. Now I can use the angle iron as my guiding rail for my knife clamp. It works perfectly.

Mom needs her knives sharpened! You are amazing! ❤😊

What an amazing attachment to get ahold of

Wow. Awesome. I may need one for this folder project.

Amazing, of course, coming from you! Nice work. Any word on when they'll be back in stock?

Wow that's awesome.

Excellent add-on. Now can you design a jig that can sharpen my wit?

I built the jig when Dennis first put out the video a few months ago. Its a great jig, I'm totally a fan, but I discovered right away that the Wen clamps do not give you the same angle for both sides of the blade. Set your angle on one side, turn over the blade, and check the angle again and its changed. I commented about this on his video at the time and he stated that the clamps are self-centering. Fact is, they are not. Nothing against him. I LOVE his channel, his style, his designs, and have learned SO much from him, but on this point he is not correct. The clamp does not center the blade and you get a slightly different bevel angle on each side. Different blade geometries can enhance this effect so that in some cases the difference can be 5 degrees or more from one side to the other, or minimize it down to one, but its always there. In order to use the Wen clamps you need to adjust for that difference by padding the bar when sharpening one side so the bevel angle remains the same. I actually got past that issue by just replacing the Wen clamp with the tormek centering knife jig KJ-45 (also on amazon). Looks very similar to the Wen clamp, and its a bit more expensive ($15 more i think), but it actually centers the blade to the shaft of the clamp regardless of the blade geometry and the sharpening angle remains the same on both sides of the blade without padding the bar

Hey I just built a revolution from the plans set I would like to chat a little I ordered belts a couple days ago so I actually finished the grinder before I had belts for it lol

This looks superb but the slightly difficult and different,

hey brian , do you ship this kit outside the USA , to Belgium ? if yes what will be the S&h fee ?

What are the lengths of round and bar stocks?

Outstanding conceptualization and execution-

That looks like it just might work!

I realize, Mower blades can be a very General and Complex statement(as Many types/styles exist). I tend to Hand grind mine on a 2x72....but this can certainly give some Human error for many reasons.....30* angle Recommended. Just wondering if U have pursued this scenario at all yet and if it may incorporate a bubble level(magnetic?) or a fixture for getting somewhat consistent grinds on the blade? So far, my practice has been to grind into the Edge of the blade, so that i can See when im at the cutting edge.....VS on a knife when using a fixture and the belt going away from the edge(and leaving a burr). Please LMK what your thoughts are...thanks!

Good time, I am Hossein from Iran, you are very polite, very handsome, and very professional

Brilliant cit…. I’m struggling to line the belt up… gen 4

Ya need to put a top platen on that platen. Too much flex in the belt... thought I showed everyone that years ago, hahaha... Have a good one, hope all is well

This looks like a very good system. I work on axes and free hand the edge -do you know of a clamp that would handle the thickness of an axe pole (1 1/2 to 1 3/4)? Thank you!

Gosh dangit Brian! You and Dennis are get me murdered by my wife if you guys keep making all this awesome stuff! Still trying to convince her to not kill me if i buy an Apollo forge kit, cuz i really want to. Great video as usual, keep up the good work!

do u give hand on training by using Tormek, belt grinfer, wetstone?!

If someone has a 2x72... They should know how to sharpen a blade! Make a product for a cheap 1x30 and that will impress me...

So can this be used on my 2x72 that doesnt go in reverse?

JIG-A-MA-RIG!!!

Who’s this guy? Looks like a great system👍🏻

Oh wow that’s the same sharpener that came with my Reeder grinder😂

Good system, but you end up with a convex bevel due to the flex and wobble in the belt. If that’s intentional great (convex edges have their advantages) but if you want a non convex edge you need a platen

Looks like we got the lighting folks from the last Batman movie to help with the intro

Jeez what I wouldn’t do for variable speed and reverse

U mention Lawn-mower blades......I would like to see this Demo.....including Mulching blades....Lets See it!

So basically you've made a kit that will make your belt grinder into a Tormek without the water to cool it.

🤓ummm, actually as you move to the tip of the blade it would be a slightly different angle that you set in the middle. This is obviously a fatal flaw 🤓🤣
