Hey KenH.
Thank you. I found a very old circular saw blade on my wife's family farm when we moved here 30 years ago in an old barn. No telling how long it had been there. It was about a 12 inch saw.
The steel is good and it takes a very, very sharp edge. The heat treating, normalizing, quenching and tempering came out great.
I've been using a lot of Wenge lately. I enjoy working with it. I sand up to 400, apply several coats of wax and then polish with a 1500 grit and buff out.
Thanks!
