I have a Buck Scoutlite that was given to me by my father when I was about 12 years old. The knife has served well for 19 years, but I no longer carry it because the tip sticks out of the handle. It has also lost 1/4" to 3/8" of blade length and maybe 1/16 to 3/32 of width. Does Buck do replacements on such items? It is made with the old (to me) 425M steel. If replacement is available, are there options for the steel?
