hey guys im kind of new to lock picking but i can pick some locks really easy like my front door which kind of scares me

. but i am having a time pick mater locks. is sabar a branch under master because i can do it in seconds? but anyway i cant do master locks. what makes master locks more difficult? what kind of picks do u recomend.(i only have 2 a tension wrench and a dimond which i made my self from hacksaw blades and a bent screw driver). how do i make them?
thanks guys
