I've been looking for a used hardness tester, but so far haven't found one. I don't make and sell enough knives to justify the purchase cost of a new one.

So, the diameter of the brass rod isn't important. I have some 1 inch diameter round bar stock which sounds like it would be suitable.

I start the secondary bevel before heat treating, but not enough for a cutting edge, leaving just a hair thin "flat" on the edge. I don't like working with a fully sharpened blade while installing the handle, even with tape on the blade I usually find a way to cut myself!

Any other suggestions to "test" the blade before installing the handle?
