layer: "La Veinette"
extracted: Coticule Quarry at Ol Preu.
size: 5cm X 15cm, rectangular hone.
natural combination hone: thickness of Coticule: 5-8mm / thickness of BBW: 8-11mm
speed with slurry: moderate (range: very slow - slow - moderate - moderately fast - fast - very fast)
speed with water: slow (range: very slow - slow- moderate)
slurry: a modest sensation of fine abrasion, typical sound of "sharpening steel" Slurry turns gray quickly.
water:a very faint sensation of abrasion.
Slurry specifics: good slurry release.
Sharpness level coming off slurry: ++/+++ (range: + shaves my armhair barely, ++ shaves my armheir well, +++ sufficient to shave my face)
Finishing properties, water only: water only: excellent. hone leaves very smooth edge. very slow edge refinement.
Dilucot: follow standard procedure. Easy to reach sufficient sharpness.
Unicot: follow standard procedure.
Touch-up hone, use with water: capable of reclaiming slightly dulling edges. 60 -100 laps depending on edge condition.
Remark: This is N°10's little nephew. Both the Coticule side and the BBW side look and feel closely the same as those of n°10. Both hones respond very similar as well. I suspect these two were found very close to eachother.
