I like Mr. Livesey's mention of a magnetic trap under the grinder. I think I"l add that to my Kally. Currently I have a 4" dust collector hose just below the work rest. It does good job for the light sharpening I do. I hear that breathing steel and abrasive dust is probably not the best of ideas. That's one thing that Tormek has going for it. Zero dust. Some messy water/sludge spatter, but zero dust.
So, when you are making a knife that requires a lot of heavy grinding to make the shape of the blade, you know, maybe a smooth taper from spine to edge or a large concave down to the edge, what's the process there? Seems like overheating would almost unavoidable when doing that much grinding.
Is the deal that the basic blade shape is created and then the blade is hardened just before the final sharpening?
What if when grinding you screw up and heat a blade enough to turn it blue. Could you the redo the complete HT/temper process and everything would be OK?
