I have a mini grip where both springs blew on mine after about 4-5 months of use... It was a pocket carry and really was a daily user for misc things. Emailed BM, and got two springs sent to me via USPS since I'm out of country (easier then trying to send the knife to the status for repair then send it back where i'd probably get charged duty again).

I was thinking of contacting them and getting a few more springs and keep them in my EDC bag for when they blow again (its not 'if' but rather 'when'). I wonder what the cost would be since it wouldn't be a 'warranty repair'?

btw: its a very easy repair and can even be done in the wilderness if you have the right torx bit.
