I'm thinking about purchasing a large Buck/Strider from someone, and I am wondering about the warantee. The thing is that the person I'm considering purchasing from has abrased the G 10 scales, and slightly marred down the finish in order to make the surface easier on the hands. What I want to know is, if I purchase this knife, does the warantee go to me? Has the warantee been voided because the scales have been altered? Also, the clip has been treated to make it black, and I want to know if THIS has voided the warantee. I'm really interested in one of these knives, but I can't afford one without a warantee with it (if you know what I mean). By the by, are all of the warantees on bucks limited lifetime?
