Work hardening? ()

Generally no. The point of HSSs is they don't change when hot. So yo could run them so hot the edge was actually red hot while working the workpiece. That is what 3V is actually good at. So you can't hurt them easily when they are heat treated. In the annealed state, if while grinding them you built up enough heat to get above the tans temp, they would air harden. But in most cases you would be hard put to do that. For instance that could happen when friction sawing them. High speed bandsawing without teeth. So don't do that. But grinding, it would be too hot to hold onto, and probably would only get that hot when grinding with a dull belt or stone. So, so long as you can hold onto it even with leather gloves, and are actually cutting, your likelihood of getting anything that hot is low. The micro edge could get that hot, but here today, gone in a second anyway.

Work hardening is what happens when metal hardens due to stuff like beating on it or bending it. So you bend a piece back and forth and it gets hard and then it snaps.
