There seem to be a number of cases where people find their chakmas are too soft for use as burnishers. I was thinking about this while I was reading some of the sharpening threads, and something occurred to me...
There is a lot of talk about how very high heat lowers carbon content in the edge metal, leading to a soft edge which disappears after a few sharpenings. Grinding away the outer layer reveals the much harder steel underneath.
Could this be the case with the chakmas? Has anyone tried 'sharpening' their chakma to see if there is harder steel lurking underneath?
