Max Knives MKO31DE — Compact OTF Automatic Knife, Double-Edged Blade

Overview

The MKO31DE is the best-selling knife in the Max Knives catalogue, and it earns that on a simple balance: a genuine out-the-front automatic mechanism, a frame that sits in the palm, and a blade that fires at the push of a thumb. The black anodized aluminium handle measures 80 mm closed and just 8 mm thick; the double-edged dagger blade fires and retracts from the front at a push of the side button.

Technical details

Double-edged stainless-steel dagger blade, plain edge, 50 mm long. Black anodized aluminium handle, 80 mm closed, overall tool thickness 8 mm. Double-action automatic OTF mechanism — the same control deploys and retracts the blade. Overall length 130 mm, weight 38 g.

Uses

The symmetrical dagger blade gives the MKO31DE a silhouette anyone recognises, and the button deployment — crisp, instant, decisive — is what makes an OTF a pleasure to own. Compact and light, it goes as easily into a pocket as into a display case. Its sibling the MKO30 carries the same mechanism with a drop-point blade: two profiles, one gesture.

Care

Wipe the blade after any contact with moisture. Keep the deployment channel clean — a blast of compressed air clears the pocket lint that is the main cause of a sluggish OTF. A drop of light oil on the mechanism two or three times a year keeps the action crisp. Store it dry.

What sets the MKO31DE apart

A true out-the-front automatic — not a spring-assisted folder — in the smallest format of the range. It is the best-selling reference in the catalogue by a wide margin: the way into OTF knives.
