I can safely say that I’ve not touched a half diamond in months… or any pick other than a short hook for that matter. I always thought that as I would become more skilled in lock picking, I would start to use all the various picks and tools, and need to buy an even wider array, but it is just the opposite. I find I need less and less, and I think I’ve fell in love with the sort hook. If it’s a tight keyway the short hook doesn’t work in, I use Peterson’s slender gem.
I guess the reasoning for this is I mostly single pin pick, while most other tools are for raking/jiggling of sorts. But I’ve actually had my brand new Falle’s for a while now, and they remain brand new and untouched. I’m not sure what I’m waiting for, I just haven’t found the need I guess.
