Attn2Detail MK3 Medium Gen 4 - Blackened Titanium - Brass Tech Screen Inlay - Harpoon MagnaCut Blade

MagnaCut Bolsterlock with Titanium & Copper Handles

The MK3 Medium Gen 4 from Attn2Detail Mercantile is a refined framelock-style folder built for collectors and enthusiasts who want premium materials and hand-finished details in an everyday carry package. This Gen 4 version brings a revised detent ramp, updated lock face geometry, and a more modern lock bar relief for improved action.

Blade

The 3.25" harpoon blade is made from MagnaCut steel with a stonewash satin finish. MagnaCut is a modern powder steel prized for its excellent edge retention, strong corrosion resistance, and toughness, making it a top choice among high-end makers. The harpoon style adds a distinctive swept spine and belly, and each blade is hand ground with the year of creation engraved.

Handle

The handle combines titanium in a grey wash finish with a brass tech screen inlay for a distinct look and feel. Titanium is lightweight, corrosion-resistant, and durable, while the copper and brass accents add warmth and character that will patina uniquely over time. At 4.51oz, the knife carries with a substantial, high-quality feel.

Carry

This model uses a bolsterlock, a titanium framelock variant where a milled bolster section of the handle locks the blade open, offering a secure and satisfying lockup. The titanium pocket clip is set up for right-hand, tip-up carry only.

Made in the USA.
