Attn2Detail MK3 Medium Gen 4 - Blackened Titanium - Countoured 20 LPI Handle - Hissatsu MagnaCut Blade

MagnaCut Bolsterlock with Titanium Handles

The MK3 Medium Gen 4 from Attn2Detail Mercantile is a hand-finished folder for collectors who want precision fit and finish along with meaningful upgrades in lock geometry. This Gen 4 build features a revised detent ramp, updated lockface geometry, and refined lock bar relief for smoother, more consistent action.

Blade

The 3.25" blade is Hissatsu-style with a harpoon profile and compound grind, hand ground and finished in stonewash satin. It's made from MagnaCut, a modern powder steel that delivers high edge retention, strong corrosion resistance, and toughness that holds up well to daily carry and hard use alike.

Handle

Handles are blackened titanium with a contoured 20 LPI (lines per inch) jimping pattern for grip, machined from a lightweight but strong material that resists corrosion. All hardware, including the pocket clip, is titanium as well. Weight comes in at 4.62oz.

Carry

The bolsterlock is a variation on frame lock construction, using a dedicated locking bolster section of the handle to secure the blade open with a solid lockup. The titanium pocket clip is set up for right-hand, tip-up carry only.

Made in the USA.
