This week on Spotlight Series we’re going to check out the QTR-5FTT folding karambit from QTRM5TR knives. With a vicious design and overbuilt frame, the Theodore, “T.C.” Calvin is a great tactical addition to anybody’s collection of folders.

The QTR-5F is only QTRM5TR’s second karambit design, after the QTR-2F, or B.A. Baracus. This model improves on that one in a number of ways, most noticeably the easier one-handed opening and more thumb-friendly frame lock. You get a nice deployment using the thumb slot, thanks to QTRM5TR’s sealed ORB pivot system. The blade is a 2″ hawkbill made from BD-4P stainless steel, and is held in place quite securely by the beefy frame lock.

Both the blade and the back side of the handle sport QTRM5TR’s Texas Tea black stonewash finish for a slick tactical appearance. The presentation side is outfitted with a G10 face scale to enhance your overall grip. Hand feel on this model is very comfortable, in either a forward or reverse grip. There’s some heavy jimping on both ends, and the finger hole is large enough to accommodate hands of most sizes, even in gloves. The low profile on the pocket clip ensures there are no hotspots to speak of.

Pocket clip is reversible, enabling a left or right side, tip-up carry. It errs a little on the side of too tight, but as such rides very securely. The finger hole sits above the line of the pocket, making for a swift, simple draw.

Overall, QTRM5TR has started to refine their sensibilities when it comes to a folding karambit, resulting in the stylish, functional QTR-5F in Texas Tea. To learn more about this knife, click here. To see our entire inventory, visit
