Apologies because I know this isn't strictly a "knife" question, but several years ago in one of my knife catalogs (I think it may have been the "mountainous" one), I saw a small tool that clipped onto the brim of a hat or baseball cap, which offered (I think) some form of cutting edge as well as a screw driver. The best way I can describe it is that it looked like a flattened pair of tweezers which friction fit onto the hat brim. No matter how hard I search, I can't seem to locate anything like this anymore, and I was hoping to pick one up as a gift for my father-in-law this year. Does this ring a bell with anyone, or does anyone have thoughts on where I could source one?
