All good stuff! The question came up on a weekend outing at a private camp site when a Senior ASM reprimanded a scout for carrying a 3 1/2" lock-blade.The ASM stated that BSA regs. state that only a "pocket knife" is to be carried by a scout. A small point yes, but this has been an ongoing discussion in the Troop for some time, and no such reg has (or can be) been produced for consultation.
