mushroom headed pins are made rounded at the top the is suppost to make it harder to push down with your picks and that.

problem is they allow the plug to rotate a fraction of a degree makng you think the pin broke but in reality it did not

plus you have to let off the tension to get past the bottom of the spool which sometimes let other pins fall back down.

you get 4-5 of these in a lock it gets tricky

actually, it's SPOOL pins, not spoiler
