The the steel in Butch's beautiful petty is reported to be Carpenter CTS XHP Alloy, which Carpenter describes as:
"(Nominal Analysis)
1.60 C, 0.50 Mn, 0.40 Si, 16.00 Cr, 0.35 Ni, 0.80 Mo, 0.45 V, Bal. Fe
Air hardening, high carbon, high chromium, corrosion resistant alloy which can be described as either a high hardness Type 440C stainless steel or a corrosion resistant D2 tool steel. Possesses corrosion resistance equivalent to Type 440C stainless but can attain a maximum hardness of 64 HRC, approaching that of D2 tool steel."
I believe Butch hardened the petty to 61 Rc, if I understand his post about it.
Using the same routine I use with carbon knives (1200 King, 6000 King, 10000 Naniwa, Dave's leather strop with .25 micron diamond spray), I am not getting the Harner quite as sharp as my carbon steel knives like the Carter funayuki.
Is there a different technique needed for stainless? Can it get as sharp as carbon?
By the way, the Harner is a delight to use as a paring knife, and gets plenty of use for a home cook's knife.
Thanks!
