... does anyone have any experience with Case's warranty? I've got a Mini Copperhead that I dearly love but the backspring is so weak the pen blade has no snap whatsoever. I'm afraid it's going to close on my fingers if I keep using it. I've cleaned the pivot and oiled it, but not seen any improvement. Is this something they would repair or replace? I've also got a Slimline Trapper that was my Father's that has so much wear on the blade it's about the size of a Mini Toothpick. I was wondering if anyone has experience with a blade replacement. I'm prepared to pay for a new blade, but I feel like the weak backspring is something that should be repaired or replaced. Please advise.
