Dictionaries define “punk” as a substance that smolders when ignited. One common use of punk is as specially treated sticks used to light fuses.
Although that definition does not really define a knife, this name has been given to an outstanding survival knife from Buck Knives. The Buck/Hood Punk is a knife designed by the late Ron Hood as a tool for survival and backwoods use. It has a distinctive style and is well designed for its intended purposes.
