  Anchoring Screwdriver Shanks - Popular Mechanics, November 1929  

Screwdriver shanks can be securely anchored in a wooden handle without any risk of splitting by merely making a slit in the shank with a hacksaw and filing the edges to sharp points, as shown in the accompanying illustration.

When the shank thus cut and filed is driven down into the handle the sharpened edges will spread, providing excellent anchorage, and preventing the blade from turning, no matter how much force is applied in using the screwdriver.

In fact, the handle will break before the shank will turn.
