I have a Spyderco Sprint Run PE Matriarch model NIB for trade. It has VG-10 blade steel and has never been used or sharpened. I want to trade it mainly for other Spyderco models but I would consider trading it for a Benchmade model 640 or 650 if one came available. I love Spyderco's Hawkbill blades as well as many of their Sprint Runs. You can contact me by PM here at BF or e-mail me.
