The reason that Gunsmith's Screwdrivers are so prized is that the tips are hollow-ground, not double-wedge shaped - so that torque is applied at the bottom of the screw slot where it is strongest, not the top. This is especially important if the appearance of the screw head is important to you.
Working gunsmiths use screwdrivers in dozens of sizes, but here is a basic set of three (tips 3/16, 1/4 & 5/16"), each 6" long with beautiful solid Rosewood handles and solid Brass ferrules. Inspiring as beautiful tools, but if you use them you will quickly discover the joy of a tip that fits the slot bottom to top. It's hard to put them down.
