How are the small 6 inch Channel Lock tongue groove pliers to carry? I saw a pair of them and they are really carry friendly.
I've posted this picture before, but if you are thinking a pliers-only pocket tool, the Knipex 87 01 125 Cobra pliers may be a possibility. They are pictured below with a Spartan and a Micra for size comparison. Pricey, but very high quality. 5" (125mm) and 3.05 ounces (85g). Not your everyday Channellocks.(Image removed from quote.)
