Well that is a bummer. I have had these sitting in my drawer for around a year or so. I think I got this box off Amazon and it would be crazy for me to try to return them this long after purchase. Lesson learned I guess.
I actually bought another box last week and they should be here later today so I will definitely open them and test for sharpness. I decided to have 2 pin dishes (I use the magnetic ones) instead of just one that I had to move every time I went from my work station to the machine and back again (I'm doing a log cabin so this cycle repeats itself over and over again).
