im new into lockpicking and have bought a nice set of slimline picks southord c2010
and when using them noticed them on a yale 5 pin i have i have noticed 1 or 2 starting to bend slightly i presume this is due to my ineperience and maybe being a little too heavy handed

i have managed to pick the yale only twice so far

so i have started to make some picks to learn with so if i brake or bend them it doesnt matter, i was wondering is bending picks common? also i am making them from starrett senior hacksaw blades.
any tips would be greatly apprechiated
thanks in advance
Rich.
