As trap disarming and lockpicking provides no XP, you may as well detonate the traps from afar. Trap Disarm kits are expensive--once a mine is detected, your characters will automatically avoid them anyway when moving. As for locked things, you could bash the door or chest--and then repair the weapon. Just some alternatives if the tools seem too limited.
I'm well aware of the alternatives, but I really want to go around disarming them and unlocking things. I love thief gameplay in RPGs and I find consumable kits to be counter productive to making that particular gameplay enjoyable. I could easily roll a wizard and just run around blowing everything up, but when I roll a Thief, I really want to enjoy playing like a thief not a wizard or a fighter.
