Just came in the mail yesterday with a new 4oz peening hammer.... I've got a week left to classes and then I'm going for a big refresh on about 14 razors. Anyone have any advice? I now have 1k, 4k, 8k, 12k and chrom-ox. Using pyramid, would I use all the stones at once with a complex pyramid pattern, or is it better to use two stone at a time, and then swap out the low grit for the next higher grit?
