Its great they got your old knife fixed up for you. I have a couple Bucklites and like them. I don't know what they cost twenty years ago, but it couldn't have been much, and for them to still repair them for free is amazing...
I've only dealt with their service dept a few times. Once was a couple 110's I sent in for Spa Treatment. When I got them back, I was less than impressed.
I posted about my experience, and quickly got a rely apologizing, and was asked to send them back in for another chance.
It was not a big deal though, as they were users, and it got me to try giving them a spa treatment at home. It was fun, and they came out nice.
The other times I have dealt with them, they went WAY BEYOND what I could have ever hoped for. When you call them on the phone, you can tell they are actually interested in hearing what you have to say, and aren't rushing to get off the phone.
It would be nice if other companies, cared as much about the customer, as Buck does.
