Mine felt the same way before I re-pinned... but one of my pins fell out on its own... they're two-part press together pins, and one wasn't pressed together well enough. So that one wasn't too bad.
As for the other, I borrowed a friend's dremel and cutting wheels and ground the heads off of mine... just be ver careful to do it slowly, so you don't tear up the handle instead of the pin.
um... if you can find a professional wire-cutter that's chisel-ground and completely flat on one side, you might be able to coax it under the head of the pin, and pop it apart that way (?)
... but don't use one that's not completely flat, or you'll spend so much time wrangling with the knife, you'll tear it up unnecessarily in the process.
Another alternate method (I guess) would be to sit it down and make threats of violence and torture towards it if it isn't cooperative... didn't work for me, but ya never know.
