Back in February I send my Benchmade Mini Griptilian to Benchmade to make use of their free sharpening service. I had the knife for about eight years or so. I can sharpen the blade, but the serrations were getting dull and I don't have the tools for that. So I downloaded the RMA form and off it went. Meanwhile I was sad like loosing a close friend. I tried to carry a couple other knives, but no love there. You find something you like, you miss it when its gone. I got a couple emails from them, one saying it had been received and then a while later another saying it was returning. When I got home from work and saw the package on my front porch, I instantly grabbed it with a smile. My knife had made it home to me. While the dogs were out doing their business, I quickly opened the package. It had a packing sheet that said a spring had been replaced. Which spring? I have no clue. As for sharp, it was razor sharp. Serrations as well. Its an excellent factory knife.
