I worked for a locksmith for years back when I was in HS. I've opened doors for my friends a couple times when they lose their keys so they come in handy. I don't drink or do anything to get in trouble for so the chance of being "caught" with them is next to zero.
That's cool man. I bought an amazing pick set from the regional SNAP-ON
distributor I built a house for. The only things that slow me up are "non-key" looking keys (barrel etc.) Often use it for letting customers into house when locked out. Works on cars too.
I just don't carry it. Not even in my truck tool box.
