>I have 14 super hard card scrapers for sale. They are thin for fine detailed work. Sure beats using sandpaper and many woodworkers think they get a better finish with them. They are 0.015" thick and 2" x 6". Hardness is 48-51C. They are similar to the ones LeeValley sells, but theirs are milled. However it is pretty easy to set these up.
I am selling them for $2.50 each plus $1 shipping. If you want more you save on shipping. It's nice to have a few when doing a project as you don't have to stop what you are doing to burnish it.
Please email me if you want some.
