I have two of the Piranta Tracer knives, one of which I use every day at work and one is with my hunting gear. The screws holding the belt clip on kept coming loose. I lost a belt clip. No real big deal, but this is the first knife I've owned that I like the belt clip idea.
I talked to Havalon about the problem and asked them what size the allen wrench is to keep the screws tightened. A few days later I got a couple of belt clips and quite a few screws with a letter telling me that if I have any other problems with their knives I can send it back to them and they would replace it if it was defective.
Too many times I've dealt with companies who have half of the customer service equation. They have a customer and are missing the service. Havalon's customer service is as good as their product.
