This is an offset half ball from the Slimline collection by SouthOrd. The head of this lockpick is bent a few guesses, which works very conveniently in narrow, small keyholes. The offset head is very useful, because it prevents the far protruding pins from being pushed too far into the lock.

The offset lock picks are often called Deforest lock picks.

Slimline lock picks are made exclusively by SouthOrd for narrow keyholes, as you often find them here in Europe. The thin Slimline picks leave more room in the keyhole.

This lockpick is 0.56 mm thick.
