Benchmade Serum (5400SBK) Dual Action Folder …

This item is no longer in production …

The AXIS Dual-Action mechanism functions like a regular AXIS lock for manual operation, but when the AXIS bar is fully pulled back the automatic mechanism deploys the blade. Benchmade has equipped the knife with a secondary safety system to eliminate “dry fire,” which occurs when a blade isn’t fully closed.

The Serum is a versatile setup with the ambidextrous AXIS Dual-Action mechanism, comfortably milled G-10 handle, and modified drop point blade. This folder has a 154-CM blade steel and a reversible tip-up carry pocket clip. Made in the USA!
