I’ve recently added another gouge to my collection, and in the process of preparing it for use have found that every time I go to hone it the edge crumbles away.
I’ve come across this issue once before on a spokeshave blade, and sent away for a replacement putting it down to dodgy steel. With this second occurence I’m wondering if it’s my grinding technique instead. The gouge needed grinding first, which I do on a fast electric grinder being careful to dip the end of the tool every few seconds to keep it cool. When it comes to honing, sections of the edge just seem to crumble away and I end up with quite big chips that need grinding out again (maybe up to half a mm).
I have a theory that, because it’s quite cold here at the moment, I might be cooling and heating the steel too much and causing fractures. I’m no metallurgist though. Has anyone else ever run into this issue before?
