I have a set of my Dad's old chisels kicking around on a shelf in the shop, they are German, the label is diamond shape and says Wolfram-Vanadium Carantie around the perimeter, with the word "Bracht" in the center of the diamond.
Anyway, I decided to "tune up" the set, now I"m not so sure! I just spent 3 hours on the first chisel. I have a 220 DMT diamond Whetstone and a Norton 4000/8000 water stone. I have an older version of the Veritas sharpening jig,
This was a long hard slog, I couldn't get a mirror finish on the back, but it appears to be flat (uniform "polish" across the entire surface). The Veritas jig worked well on the bevel, and I was able to put a microbevel on very easily. When all is said and done, I can shave the hair on my arm with the chisel, now I should try it on some wood.
I know that I'll "only have to flatten the back once" but I wonder if I"m doing something wrong to take this long. Six more to go! Wrists back and elbows are all a bit sore from all the stone work.
Thanks for your help.
