we probably don't use enough pins., We tend to get too confident in our ability to do accurate peicing, or get in a hurry.
......and then when you get a whole bunch of different kinds of pins in a box, sort them and toss those out that you don't enjoy using, or if they get bent don't try to straighten them out as I do, or if they get dull, toss.
I went out and bought new ones recently and threw the old ones away. Much less frustrating.
