For what its worth....I have seen a lot of Buck knives, especially 110's, that have been customised by other companies. From what I hear, the quality is great but...except in some special cases, they do not have a Buck warranty anymore. The reason is that if someone actually used one of those knives and broke the blade somehow, we would not be able to remove the old blade and install a new one. We tried this one time, out of the goodness of our hearts,

and the custom inlay broke into a million pieces. Even though the blade was used as a pry bar, causing the break, we wanted to reblade it as a courtesy. The customer didn't see it that way and was very upset. So, to make a long story shorter, we spent about $200 to repair his non-warrantied knife.
Rant over...
