I've read a few horror stories about shipping a tool back to the manufacturer for warrant issues... Usually the issue is with the post office and a shipping envelope... I would think a small box would be as bad... I have a Leatherman PST2 to ship back, and I really don't want to go thru a insurance hassle if it is lost in shipment... So what have you guys used?... If boxes, what size?... Leatherman's warranty is great, but does me no good if the tool is lost in the mail.. Thanks for your help... Butch
