Heat treatment was a bit difficult because I was struggling to see the colour change. Back home I cleaned and shaped with my flap disk and ground and polished cutting edges. On the lathe these new chisels are and order of magnitude better than my bargain basement tools. They take and hold a great edge and their mass dampens any vibration. The skew chisel particularly produces a good clean finish which was remarkable considering the trouble I had with my old chisel.
I had ground chip knives from old files before but they have never been any good. The hard material would simply fail when it became too thin either during the sharpening or during the first cut. The tempering on my new knife worked a treat softening the material so that it will hold an edge. Both the knife and the spoon gouge cut well and forging is the only practical way I was ever going to get the right shape.
