Description

The Benchmade Infidel 3300 is a tactical automatic knife designed by Bill McHenry and produced in the United States. It uses a double-action out-the-front (OTF) mechanism, allowing the blade to deploy and retract through the front of the handle using an ambidextrous thumb slide.

The blade is a double-edge spear-point design made from D2 tool steel hardened to approximately 60–62 HRC, offering strong edge retention and durability for demanding cutting tasks.

The handle is machined from black anodized 6061-T6 billet aluminum, providing strength while keeping the knife lightweight. Additional design features include a removable deep-carry pocket clip and an integrated cleaning port, which allows debris to be removed from the internal mechanism for improved reliability.
