Editor's Note: This Black Triangle G10 knife review was originally published in Issue 24 of our sister publication Concealment.
WHAT IS IT?
It’s a G10 knife with a nonmetallic sheath designed for discreet self-defense.
WHAT GOT OUR ATTENTION?
Every Black Triangle knife comes in a retro VHS tape box, complete with a custom-printed, faux-aged insert that looks like it belongs on a late-1980s Blockbuster shelf next to Predator and They Live. Packaging is usually a throwaway item, so we were interested to see if this attention to detail carried over to the box’s contents.
HOW DOES IT WORK?
For those who aren’t familiar, G10 is a hard fiberglass composite material that’s commonly used for handle scales on metal knives. The Creeper MK1 Mod 2 is constructed from a solid piece of ¼-inch-thick G10 ground to a sharp point. Its handle is wrapped tightly in gutted black paracord, and it includes a fitted Kydex sheath. The polymer belt clip is bound tightly to the sheath with elastic cord, eliminating the need for any metal hardware. The end result is a G10 knife that’s completely invisible to a metal detector, so it can serve as a self-defense tool in environments where a traditional knife or firearm might not be permissible.
We also received a sample of Black Triangle’s matching MK1 trainer ($42), which is made from easily identifiable blue G10 with a blunt tip. A fitted sheath is also included with each trainer.
HOW WELL DOES IT WORK?
Many nonmetallic tools still register on a metal detector due to carbon-fiber construction, metal sheath hardware, or other overlooked elements. Thankfully, that’s not the case here — we passed a wand over the Creeper repeatedly without a single beep. Note that nonmetallic tools can still be found by density scanners or a simple pat-down, so there’s no guarantee it won’t be noticed, but it’s much more concealable than a metallic blade.
WHAT WE LIKE:
The Creeper’s handle is large enough for a full-fist grip, and the twisted cord wrap offers plenty of slip-resistant texture. Sheath fit is just right; the knife clicks securely into place but is easy to draw quickly. The belt clip accommodates a standard 1.5-inch belt, and the extra loop of elastic cord attached to it provides an alternative retention method. It can be tethered to a belt loop, the inside of a pocket, or any other fixed point to ensure the sheath stays put as the knife is drawn. That versatility is helpful.
Black Triangle has a lifetime guarantee for every G10 knife, so if the tool or sheath is broken or damaged, they’ll fix or replace it.
We appreciate that Black Triangle offers a trainer that perfectly replicates the size, shape, and weight of the “live” blade. Too many of the trainers we’ve used in the past feel like featherweight toys compared to their real counterparts. We’re also glad it includes a fitted sheath that allows you to practice the drawstroke realistically. An inert trainer is an important add-on for anyone who wants to practice edged weapon techniques safely against a human partner.
WHAT WE DIDN’T LIKE:
The edge geometry of any knife is a compromise between sharpness and durability. A fine edge slices effortlessly, but dulls or chips quickly. This is especially relevant for G10, a material that’s less durable than steel. Black Triangle grinds each G10 knife to be strong enough to puncture repeatedly, acknowledging that they’re “point-driven, meaning they are not meant for cutting.” The Creeper won’t be effective for slashing, but that’s not a problem as long as your fighting technique matches this design.
