Like Drew said it is possible but got to get it pretty hot. I’ve never tried sanders on a knife so I’m definitely not any kind of an expert on how easy or hard it is to get that kind of heat. Diamond and Arkansas stones are all I’ve got. I haven’t gotten to play with the new angle much so not sure how well it will hold up to use. I plan to use it this weekend as much as I can and see how the edge holds up.
