All my lathe knives are HSS. I have an array of sharpening tools (four stone, variable speed, reversible grinder, 1″×42″ belt, a standard grinder, a Delta water stone a couple buffers and accessories for my lathes. In the end, I use the 1″ × 42″ religiously, but that may change, after I get my sharpening jigs.
For my Spydercos and my kitchen knives, I use an Edge Pro, but frequently touch up with the buffers.
All of these make FAST work of my HSS blades.
