Mercharness – Concealed Carry Harness for Kydex Sheaths
The Mercharness is a concealed-carry harness that converts any kydex-sheathed fixed blade into a comfortable, shirt‑level shoulder holster. Designed for minimal profile and maximum comfort, the Mercharness lets you carry concealed beneath a t‑shirt while keeping your tool secure and instantly accessible.
Made from MIL‑SPEC 550 parachute cord and engineered for movement and comfort, the Mercharness eliminates metal hardware that pinches, avoids bulk from clips and buckles, and rides with your body for natural carry. It can be configured for strong- or weak-side wear, adjusted on the fly even while being worn, and allows a smooth draw without an additional tie‑down—making it ideal for daily carry, off‑duty concealment, or minimalist EDC setups.

Great for EDC
I use a fairly small fixed blade for edc and this harness is great for days when I'm not wearing a belt. Very unobtrusive and the sheath hangs free so clothes don't bind up. Only thing keeping it from 5 stars was that the ends were melted into a rather large glob, easily fixable and did keep the paracord from fraying though.
