I have made a few more screwdriver handles for the flintlock builder and user. The tool feels good in the hand. It includes 3 of the most used straight bits that will accommodate most common interior and exterior lock screws such as side plates, flint clamp, frizzen, and cock screws. The screwdriver handle is hollow and will hold extra bits. Each bit has a steel ball detent and they fit in the shaft precisely with NO play. The 1/4-inch hex shank hollow ground bits are made in America of American steel, heat treated, and black oxide coated. Each has a steel ball detent and is marked with a model number. A brass driver with 3 bits cost $63.00 shipped in the USA. I accept cash, personal checks, money orders or zelle transfers for payments. PM me if interested.
The bits are made by the Chapman manufacturing company in Durham, Connecticut
(no affiliation). They have been an American manufacturer producing tools since 1936. I have used their drivers and bits for many years and never broken one. Each bit is marked on the shank with a model number for easy reference to the bits available on their website. The bits available are listed with width and thickness dimensions. They cost $2.00 each with reasonable shipping costs. They make 15 different straight blade tips if you want to expand and of course many other style bits.
