I noticed that some short hook picks are relatively linear down the shaft; however, some get significantly thinner and dip just before the hook. Are these both short hook picks and which would be better for lockpicking? I assume that the one with the dip may help prevent oversetting the pins?
Also, how thin do you guys think I can sand my metal before it becomes too weak and yields? I'm using spring steel from windshield wiper blades (about 1 mm to start with).
Thanks in advance!
