Just found that Spencer Reiter has his Blog updated with SAR Signal Tags for sale again: http://sarglobaltool.blogspot.com/ I saw one of these here on the Forum recently, but my "search skills" must not be too good since I couldn't find the thread. I guess I really do need one of these signal tools, so I just ordered a stainless GI dog tag style one for $25 including shipping. Looks pretty high quality. There are several kinds of dog tag tools out there, made by individuals and companies; some very functional. Anyone got a collection of them?
