WTH are you talking about?
you were in school and suddenly a lock materialises in front of you, and happens to be a high security lock??? then you just take it home??
hehehehe... if a 7 pin version of the tubular pick is for 7 pin tubular locks. and the same applies to 8 pin tubular locks...
... then what on earth could a 10 pin tubular lock need to pick it? ....
yup that's right, a 10 pin tubular lock pick.
This tool will cost you a lot of money, and it is hard to find because you are not meant to be messing about with these locks, unless you are a locksmith, or have a designated purpose.
are you trying hard to be a fuckwit or something?
