Don't settle for mediocrity.
That is one of the problems with buying something online, someone sends you an item in less than the condition that it should arrive in and rather than go to the trouble to send it back, most people just settle for what they got.
Me, I would not only send it back, but really let them know how displeased I was with their service.
But that is me
If you get no satifaction out of them, let them know that you are going to post your disatisfaction on Blade forums.
If nothing happens, use the knife until it breaks the pins or falls apart, and then save the blade.
I'll buy just the blade or broken knife from you for $5.00 to $10.00 depending on the blade's overall condition.
Or I will rebuild the knife with new hanldes for a reasonable price.
