Ok, learn from my mistake...When I ordered (12) I put in the remarks section to please not send me any flints with the dreaded hump, that the last order I had 3 that were useless to me as they would not fit in my lock..This afternoon my order shipped and dang if they didn't notate that if I wanted hand selected flints, I should have ordered hand selected flints...It will be interesting to see how many useless flints I get this time...I do plan to send them back if there are as many as 2-3 more...Lesson learned, pay .20 more a flint, order them singularly so they can hand pick them for you...
