I have to toss this out here for you guys.
I have a Stone River ceramic folding pocket knife, and I love the thing. Some time ago the tip snapped off of it and I was pretty disappointed with myself because this was my favorite daily carry pocket knife.
I contacted the guys at Stone River last week, they asked me to send it in to them. I shipped the knife and tracked the package, it showed it was delivered today. I contacted Joe, the guy I spoke with originally, who told me that a replacement has been shipped out already, the same day they got it.
Fantastic customer service, highly recommended.
