12K Chip Removal/Bevel Setting
12K Super Stone Chip Removal/Bevel Set
Recently in another thread I talked about the aggressive ability of the Nanawa 12K Super Stone. So I thought I would document a chip removal, bevel set using only the 12K Super Stone.
I picked up this very nice Henckel, Platinum 5/8 hollow ground razor from an Antique Swap Meet, (Photo 1). The razor was in good condition, but in need of cleaning and honing. Two large chips were in the edge, one near the toe and the other mid blade. They were marked with a red sharpie for easy locating, (Photo2 & 3)
I cleaned the razor with WD40, 0000 steel wool and a paper towel, then polished with Mothers and Maas Metal polish, (Photo 4)
Resting the razor on the spine on a piece of foam, I lightly bread-knifed the edge with a 600 grit diamond file, 3 lite strokes nearly remove it completely, (Photo 5 & 6)
I then did 4 sets of 20 circles, 80 total and checked the edge after each set of 20, (Photo 7).
Circles work well for removing metal at bevel setting with a bit of pressure, because as you perform a circle you are using a multi directional stroke that changes stria pattern continually and speed up metal removal.
Once the bevels came close to meeting, (Photo 7), I switched to Alex Gilmore’s method of 20/10/5/3/2/1 half laps and did 4 sets, (41 laps per set), checking the edge after each set, a total of 164 laps to where the bevels were completely meeting.
I stropped on Chrome Oxide Sail Cloth hanging strop 25 laps, and did another 2 sets of 21 laps, 10/5/3/2/1. I lightly jointed the edge after the first set to remove micro-chips and, with very lite pressure to finish the edge with another set, in 21 laps, a total of 42 finish laps. (Photo 8, 9)
Stropped on leather and .50 CBN and shaved. Very nice razor, a very nice, keen and smooth edge.
A total of 80 circles and 206 half laps total, about 20-30 minutes from start to shave, if I was not photographing. So, as I said, the 12K super stone is a very aggressive and versatile stone capable of much more than we challenge it to be.
I have done much the same thing with a Norton 8k and re-set bevels on the 12K in under 100 laps, after lite bread knifing. For most it should be their first stone, and possibly the only one, they will need unless they get into restoration or a lot of honing.
