Hi Josh thank you! The air profiler can handle a variety of stone sizes, but works best with 1/8" thick stones. They're all 6" long (you just snap pieces off to the length you want with your hands that is most comfortable to use). For width I recommend at least 1/2" wide, if it's not wide enough it'll take way longer to sand/polish and be pretty miserable. I made the mistake of buying some 1/8" wide stones and they just sit in a corner of shame. Wider will cover more surface area and be more efficient. I'm currentlly using 1/8 x 1/2 x 6

@@transparentknives OK that's great info thanks man! What's the highest carbide steels you have tried those stones with? Magnacut/cruwear I imagine would work but s90v/10v not so much probably. I wish someone made sintered diamond stones for this application... I know BBB had some sharpening stones made that were a diamond water stone that would be sick for high carbide steels

@@REKKnives the highest wear resistance ive tried is only m390 at ~64 HRC (still more wear resistant than MagnaCut at 65 HRC). I havent wanted to find out how long it would take to do s90v or 10v yet 😅

I have not tried those yet, if they are higher friability and sufficiently abrasive they might cut faster. However the would definitely not last longer, as high friability would mean they break down quicker. I haven't done a true stonewash but I would guess around 1200 would be fine for that as well, what might matter more is the type of tumbler and media you are using at that point

The 1 micron paste is aggressive enough to polish, I'm using really light pressure and not buffing for very long when removing the swirlies so I don't bother. If it's a knife with saber grind or partial hollow when you're doing the main bevel with the dremel you'll polish the flats somewhat. My solution to that is to leave the blade 1 thou thicker stock thickness than final thickness before polishing then surface grind half a thou off each side to final thickness to remove any polish marks on the flats. Painters tape works for covering stuff you dont want polished though

I don't buy all the grits, just the ones I plan on using. Will depend on your process but 320, 600, 900, 1200 is nice to have

I've never tried the airway buffs, but I can give them a shot in a future video. They are probably good for airflow. But it definitely can't take 400 grit to a nice mirror, there are no shortcuts.

They probably can get you that mirror polish (with a bunch of ghost 400 scratches) while at the same time rounding over all of your corners. That happens right before the buffing wheel flings the blade into your chest

@@steveballzack1409have you used them?

There should be separate links for the stones, which are aluminum oxide, and the diamond pastes that are used after.
