Video - thinning out primary grind and lowering inclusive angle

[HeavyHanded]

Hello, another sharpening video(s) complete with poor composition and painful monologue, but with better resolution!

Working on a boning knife from my inherited kitchen set that still doesn't perform well despite lowering the inclusive cutting bevel. Decided to do a quick (for the job) grind down of the primary bevel face and resharpen, has worked wonders for the rest of the set.

Starting at 120 grit wet/dry and finishing on plain paper over a Washboard. Normally would use a heavy machine stone for the initial work but did it all WB to cover a few points of interest.

Thanks for watching!

Nicely done! I am surprised however that you did not use our trusted Norton Crystolon stone for that stock removal!

The other two in the set that need thinning I used the boat stone pictured below (Norton 61463610369 80 grit) to rough it and then both sides of the Crystalon stone in series - finished it all off with some Washboard stropping/refining using the reclaimed grit off the fine side of the Crystalon. End result was very similar. Is one step removed from the stock compound on paper and a great all around edge. On my kitchen knives only the Chef's knife reliably gets the stock compound as its a dedicated chopper. The rest sometimes get the compound, sometimes the grit off the SIC stone. The reclaimed grit off the fine SiC stone does a great job for general purpose and is a bit more toothy than what the compound produces. Can still zip right through a hanging paper towel just like the boning knife in the video. I used the WB start to finish just to touch on some usage issues - it can get it done but you cannot lean on it the way you can a vitreous stone, so it takes a bit longer on the heavy stock removal.

I came across a box of these at my local ACE hardware a few years back for 12 bucks a piece, is a beast. That's the stone I used to manually convert an overbuilt sabre ground TOPS sheath knife into a full convex (is my current EDU).

100% by hand - It will be a few before I tackle something like that again, I even ground the swedge into a clip point by hand...
