  • where do you buy this stone?

  • @Roger1379 I did some quick research, and you're correct about the burr being removed, but it didn't say that the burr was when the metal folds over. "A burr is a raised edge or small pieces of material remaining attached to a workpiece after a modification process" while reading I found a technique that I sometimes use, but had no idea anyone else had the same idea. I'd sharpen the edge, and then slice into a piece of fabric to remove unwanted metal debris, then repeat on a finer stone.

  • @mawkheaf A burr is when the metal folds over, if the metal is folding over, it therefore is not as sharp as it can be, no one leaves a burr on the edge as the final process unless they want a dull knife.

  • @Roger1379 also if you're into edges I suggest looking up obsidian. Obsidian has the finest and sharpest edge that can be crated with our existing technology. Metals can never have a "perfect" edge; if you look at a metal edge under a microscope you'll see lots of nicks, bumps, and holes that create drag when cutting. Obsidian has far less "imperfections" than even the best metals out there. some surgeons use obsidian scalpels to reduce scarring, and make more precise cuts.

  • @Roger1379 I dont think you're correct. He obviously knows the knife is not polished because he hasn't honed or polished it yet. He's feeling the bur is and will probably hone and polish it after. a properly SHARPENED knife will always bump and bite, until you hone the BUR into alignment, and polish. leaving the BUR rough is useful for cutting tomatoes and other things that have a thin skin waxy skin, because its roughness tears through the skin instead of gliding over it.

  • now thats a knife.

  • This is a great video, thanks! I just got moved to sushi bar a few months ago and am still working on sharpening technique. Very useful

  • His not putting the blade against his finger nail for the "finger nail test", his running it down the finger nail to see if it is polished, when properly sharpened it should feel like glass, if it's not properly polished you will feel it bump and bite in a bit.
