Corby Bolts – Brass (Knife Handle Fasteners)

Corby Bolts – Brass (Knife Handle Fasteners)

Medium-strength mechanical fasteners used to secure handle scales to full-tang knife blades. Corby bolts are commonly used in addition to epoxy, providing both a clean visual finish and significantly increased mechanical strength compared to standard pins.

Each Corby bolt consists of two threaded brass pieces that screw together through the tang. Once tightened, the ends are ground flush with the handle scales for a seamless finish.

Available in two sizes to suit different handle thicknesses and knife styles.
