hardness tester help
I as thinking about obtaining a hardness tester to check my blades after heat treat and tempering is complete. Since I make knives more for a hobby, I don't have a big budget. I've sold only 7 knives. (Two more being made right now.) Also I have a small shop, and there isn't much room left, so I was thinking about a hand held tester.
I could use some advice on just about everything regarding these testers, I've never used one before, so simple operation would be useful.
Which are the good manufacturers?
What do I really need or do I even really need one?
Are the hand held testers any good?
Any advise would be greatly appreciated.
