Half of QSP's line comes with a glow-in-the-dark handle, and the question is whether that is a gimmick or a feature. It is a feature, for a narrow set of reasons, and a look the rest of the time. This guide covers how the glow works, when it actually helps, and the knives we stock with it.
How it works
Strontium aluminate pigment in resin, G10 or a micarta inlay absorbs light and re-emits it for hours, brightest in the first thirty minutes and fading to a faint glow by morning. It is the same pigment as watch lume and exit signs. It does not wear out.
When it helps
Finding the knife on a nightstand, in a tent, in a dark truck cab, or on the ground after you dropped it. Anyone who has lost a black knife in the grass at dusk understands. It also helps a knife on a bench full of tools.
When it does not
In a pocket, it is invisible. In daylight it is a pale green or cream handle. It will not help you find a knife in a bag.
The knives
The Penguin in glow resin, the Coyote in glow micarta or G10, the Elk in glow burlap micarta, the Mantis in glow G10, and the Peregrine with a glow inlay. Full glow handles are the brightest; inlays are subtler.
Worth it
If the knife lives on a nightstand, in a tent or in a truck, yes. If it lives in a pocket, buy the color you like.
