sharpening a serrated knife in 90 seconds - knife sharpening

http://www.permies.com

Ray, "the edgemaster" demonstrates how to sharpen a serrated knife blade. The tip was sharpened the way you would sharpen a normal knife blade and then he used almost exclusively the power rag buffer wheel.




He said something about getting a wire edge or a feather edge that I didn't understand. Nor did I understand what he was doing by running the knife on the wood every ten or fifteen seconds.

When i handed him the knife, I knew that blade was very dull. I had stopped using it months previously because it was useless and I could sharpen the other blades. I was thinking that I would need to learn how to sharpen the serrated edge first. I'm glad I bumped into "the edgemaster" - because what he handed back to me was crazy sharp. Razor sharp. He says he polishes the blade to what it is supposed to be.

This is my leatherman wave tool.

Ray was standing in missoula, montana when I took this video.

anybody know what he is doing running the blade on the wood every ten seconds or so?

[paulwheaton12]

anybody know what he means by "wire edge"?

[888bobdaduck]

@paulwheaton12 testing sharpness i suppose...

@paulwheaton12 He's removing the burr

[CSVickers1984]

@paulwheaton12 He is honing the edge, (the grinding process has a tendency to heat up the metal and bend the edge of the blade over like the crest of a tidal wave,) so that it straightens out again. If he didn't do that, grinding the second face of the blade would nibble away the sharpest part and essentually dull the blade overall. It also has the function of sweeping away any fine grit from the surface, making for better contact between metal and grinding wheel.

[AdUtrumquePeratus76]

@paulwheaton12 wire or feather is the small bit of steel that protrudes past the point where the planes of the edge meet. The buffer brings the"wire" up and off the blade, this feels sharp, but the wire or feather will bend over and the blade wont cut. running it over hard wood removes the wire and re buffing polishes the true cutting edge.

@paulwheaton12 It looks like he cuts a bit edge of the wood briefly to test how sharp it is. Pause at 00:54 you can see other cut marks.

@paulwheaton12 getting rid of spurrs in the metal..

Nice video i havent seen one of those old school knife sharpeners in about twenty years.

@paulwheaton12 Getting rid of the small bit of metal left behind?

[vutEwa]

@paulwheaton12 would adding cellulose (wood) to the mix provide an extra boost of cleaning power as it steams off the blade?

I think he's referring to the burr that builds up on the back of the blade as you sharpen. See the diagram marked "burr" . Youtube seems to block URL's in posts, but if you google "burr" with sharpening you'll find it quick enough.
