So after using the Matsumura White Paper chisel I planned on ordering some more from fine-tools. Something went wrong and the order didn't get through so I now have the time to do some more research before buying more chisels. I've read on toolsfromjapan that the Fujikawa professional line of chisel is well regarded by carpenters in Japan and the price is very reasonable. Does anyone here have some experience with these chisels? They're supposed to be very hard (68RC) so I was wondering if they're a pain in the bottom to sharpen and how the cutting edge holds up?
