I just recieved a shinto file from amazon in the mail......I was hoping that it would work good on desert ironwood for rough shaping and stock removal on handles....went into the shop and put a block of ironwood in the vise and give it a try......looks like it is going to work great.....I was avoiding using a lot of ironwood because of the way it would plug up belts and regular files but i think this tool is going to be a game changer......anybody here been using the shinto files for any lenght of time and have an opinion?
