Benchmade Knife Mechanisms
Understanding opening systems, locks, and everyday operation
The mechanism in a knife affects far more than how it opens. It influences safety, ease of use, speed, and how naturally a knife fits into daily carry. Whether you prefer deliberate manual control or fast deployment, understanding how different mechanisms work makes it easier to choose the right tool.
Benchmade offers a wide range of opening and locking systems, each designed around specific use cases. This guide provides a clear overview of the most common mechanisms you’ll encounter and what to expect from each.
Knife Mechanism Types

Description |
|---|---|---|
AXIS® Lock |
Manual |
Benchmade’s proprietary ambidextrous lock. A sliding bar engages the blade tang, allowing secure locking with smooth one-handed operation. |
Slip-Joint |
Manual |
Spring-tensioned mechanism without a true lock. The blade is held open by backspring pressure with defined open, closed, or half-stop positions. |
AXIS® Assist |
Spring-Assist |
Uses a torsion spring to assist blade deployment after initial movement, providing controlled and smooth one-handed opening. |
Push-Button Auto |
Automatic |
Spring-loaded blade deploys at the press of a button and locks open until disengaged. Designed for fast, deliberate operation. |
Auto AXIS® |
Automatic |
Automatic version of the AXIS® Lock. Pulling the AXIS® bar releases the blade while retaining ambidextrous control. |
OTF (Out-the-Front) |
Automatic |
Blade deploys forward and retracts into the handle using a sliding switch that controls internal springs. |
Fixed Blade |
Manual |
Single-piece construction with no moving parts. Offers maximum strength and reliability for demanding tasks. |
