I've been trying to buy various old dirty carbon on the bay and at thrift shops, they are great fun to practice thinning and sharpening on and after I am done they make awesome presents - wish the prices haven't gone up so much of course But even at current prices, a 30$ forgecraft thinned and hand sharpened has be the equivalent of a low end carbon steel J-knife, no??
Forgies are pretty hard though, the wonderful folks at Bloodwrrot tested a bunch of mine for me and none were less then 58 or 59 and the chefs knifes were 61 or so.
Still I am often curious how hard the steel is on some of the other knives I pick up. The stones I use cut so quickly that time on the stone isn't a great measure. So then I got to thinking, isn't ordinary window glass mid 50's in HRC? If so can I use the idea of scratches glass pretty easily = probably at least 57-58. Doesn't do anything = really soft < 55?
