A larger EDC knife usually makes you pay for the extra cutting reach in your pocket. More blade tends to mean more handle, more steel, and enough added weight that a knife eventually stops disappearing into daily carry.

The QSP Mantis takes a different approach. The black G10 version pairs a 3.42-inch Nitro-V blade with a 4.5-inch closed length and a listed weight of about 2.75 ounces. Open, it measures 7.92 inches overall.
Those numbers are the Mantis’s clearest selling point. You get more than three inches of blade without carrying a particularly heavy folder.
The Modified Tanto Is Not Just for Looks
QSP gives the Mantis a modified tanto blade rather than the familiar drop point found on many EDC knives. The design creates two noticeably different sections of cutting edge, resulting in a straighter overall profile than a blade with a broad, sweeping belly.
That shape can work well for cardboard, tape, cord, packaging, and other utility jobs where a long, straight section of edge is useful. The 3.42-inch blade also offers enough reach that the Mantis should not feel like a tiny secondary knife.
There is a tradeoff. Buyers who regularly slice food or prefer a pronounced belly for sweeping cuts may find a conventional drop point more natural. A modified tanto does not automatically cut better simply because it looks more technical.
The practical question is whether its geometry suits what you normally cut.
Nitro-V Is a Sensible EDC Steel, Not Magic
The Mantis uses Nitro-V stainless steel, a material that has become increasingly common in mid-priced everyday-carry knives. It is a balanced knife steel, rather than one designed around a single extreme characteristic.
It would be easy to turn that into broad claims about toughness, corrosion resistance, or edge retention, but the steel name alone cannot establish how this particular knife will perform. Heat treatment, blade geometry, edge angle, and manufacturing consistency all matter.
For buyers, the more useful takeaway is simpler: Nitro-V is an established stainless steel rather than an unidentified budget alloy, and it is commonly selected for working EDC knives. That provides a clearer sense of the steel category QSP chose, but actual edge life on the Mantis would require testing rather than assumptions based on a specification sheet.
You Get Two Ways to Open It
The Mantis uses both a rear flipper and thumb discs. In a hands-on review, the tester found the flipper easy to operate and said the thumb discs worked quickly after a short adjustment period.
That is useful evidence, but it represents one sample and one user’s experience. It does not prove every Mantis will arrive with identical action or detent tuning.
The dual-deployment setup still has a practical advantage independent of that review: you are not committed to one opening method. The flipper offers a familiar option, while the thumb discs let you open the blade without relying on the tab.
A liner lock secures the blade when open, using a familiar, straightforward mechanism for an EDC folder.
G10 Helps Explain the Low Weight
The black version uses G10 handle scales and a reversible pocket clip. At about 2.75 ounces, the complete knife is relatively light considering its 3.42-inch blade and 7.92-inch overall length.
QSP also gives the handle more aggressively textured sections instead of leaving the G10 completely smooth. That can provide extra traction in the hand, although texture creates its own carry compromise.
The same reviewer who praised the knife’s handling found the combination of scale texture and clip tension somewhat snug when sliding it into and out of a pocket. He suggested frequent carry in the same pants could eventually produce wear. That should be treated as an observation from one knife, not proof that the Mantis will damage everyone’s pockets.
The reversible clip is another useful detail, although it is not a true deep-carry setup. Some of the handle remains visible above the pocket. Whether that is a drawback depends on whether you prioritize discreet carry or easier access.
Who Should Buy the QSP Mantis?
The Mantis makes the strongest case for buyers who want more cutting reach without carrying a dense, heavy folder. Its 3.42-inch Nitro-V blade and roughly 2.75-ounce weight create an appealing size-to-weight balance, while the G10 scales, liner lock, flipper, and thumb discs keep the overall design straightforward.
It is less obvious for someone who wants the deepest possible pocket carry or strongly prefers a traditional drop-point blade. The textured G10 and modified tanto give the Mantis more personality, but those choices also make it less neutral than some general-purpose EDC folders.

The QSP Mantis is worth considering if your current EDC feels either too short or too heavy. Its appeal is not that Nitro-V or a modified tanto automatically makes it better than every rival; it is that QSP combines a 3.42-inch blade with a roughly 2.75-ounce carry weight. For everyday jobs such as boxes, cord, tape, and packaging, that balance is the reason the Mantis stands out.
