    SV30 on Shapton Glass results

    The usual advice is to use more pressure to release dulled grain, you advocate using nagura more often instead. Makes sense, the nagura is harder than any knife so it will do a better job. Yeah I use 400 grit for 2k GS. At that point, if I was seeking an even flatter, flawless grinding...

    lost two knives trying to straighten by hammering (a few days) after initial quench. they where ground a bit too thin and austenitized in a forge, hence the distortion. the first knife, spring steel, was indeed very easy to bend at the spine but chipped badly at the edge (although not...
