The composite hand drill (CHD) is the supreme hand drill design. The sacred plant which drills fire most readily is rare, and its stems are not found long and straight enough for making regular hand drills. This is the reason for making CHDs. A mainshaft is from another plant forming naturally long and straight stems. Into the mainshaft is inserted a short section foreshaft drill tip. One end of the mainshaft forms a drill chuck which holds the easily replaceable drill tip. The drill tip is simply fastened by tying with a string. No glue is needed. I can photo one of my CHDs if people need see the chucking design. Here is the list of local materials most adequate and available in my area: Mainshaft of horseweed, fastening string of stinging nettle fiber, drill tip of California Buckeye, hearthboard of willow. Our magical drill/hearth material combination is tribal secret. I carry a CHD of this combo only 18 inches long. Nearly easy as striking a match.
