I stopped by the SFO last week. Michael helped me out with an issue on a Ronin 2 and its sheath. I wandered around the store while Michael took out other new knives & sheaths and evaluated the problem. I circled back around a few minutes later and he had the problem solved, the knife and sheath were now seeing eye to eye. We boxed up the knife and sheath when I noticed the box was a new one. I thought my old original box had gotten swapped with a new box somehow and, actually, it did. Michael couldn't get my original knife and/or sheath to play nice with any combination of other knife or sheath so, he exchanged the knife and sheath for new ones, under warranty.
Then, we spent a few minutes checking out a "customized" Delica of his. (Ahhh, the benefits of working at Spyderco.
