Thread: NOS Herder!

Randy, Thanks for the update. Keep posting about what to do to refine the blades. This does look like a fun project.

One of the tests chipped the blade along the edge. From that Mike looked at the grain size and said it is a fine grain steel. We talked a bit about what needed to be done re heat treating and he suggested a 2 hour temper at 400 degrees just to be on the safe side.

The razor appears to have had the "flashing" from the die ground off but there is still a lot of grinding to go. The razor blank has been formed for a 1/1 or full hollow, bi-concave grind. It is not a 1/4 hollow, single concave grind now and due to the thinness of the grind below the spine it probably cannot be made into single concave grind, wedge without also grinding away some of the thick, deep spine. I will play with the chipped razor, shortening it and grinding it on an 8" wheel to see what happens.

I will report back in about one week.

What's happened in your work with these blades. I have not started to work on mine yet- time factors as well as waiting for suggested starts (heat treating, tempering, etc.)
