I use a 220 grit belt and the area just below my leather platten to convex the edge. I am running the grinder slowly and often dipping in water. After the 220 belt I switch to an A45 Trizact belt to blend the convex and further refine the edge.
Following the A45 Trizact belt, I use a cardboard wheel with white compound to polish the edge and remove the bur. The final step is to hand strop the blade. I use Simichrome polish as a stropping compound. I apply a thin film to the strop and let it dry. I believe this is similar to a pink scratchless compound. I next test the blade for shaving sharp and then whack on some oak and cut rope with it.
I use an electric etcher to apply my mark. After etching I use the A45 trizact belt to clean up the etched logo.
I sand the backs of the bolsters flat and then I use temporary pins to hold them for shaping. I still use my Craftsman 2x42 grinder for some grinding tasks.
I have used 120 grit paper on a leather backed file to further shape and polish the bolsters. Even though there will be further grinding after the bolsters are peened, I sand as much as I can at this point to minimize the potential for grinding issues.
