At first glance, the Fallkniven U4 appears a modest penknife—unassuming, almost simple, the kind of knife you could draw from your pocket without raising an eyebrow. It is the sort of tool you might use to peel an apple, slice cord, or open a parcel. But appearances, as with many of Fallkniven’s designs, can be deceiving. Look closer and you’ll find a blade of high-grade powder steel, a material chosen for its exceptional edge retention, corrosion resistance, and sheer cutting performance. This is not a knife built for show, but for lasting use, a hallmark of Fallkniven’s philosophy.
Fallkniven, based in Norrbotten, Sweden, has earned its reputation supplying knives to Swedish Air Force pilots and military units, designing tools tested in some of the harshest environments on earth. Every knife they produce is the result of rigorous research, testing, and refinement, and the U4 is no exception. It embodies their ethos: compact, efficient, and deceptively strong.
In the hand, the U4 reveals its cleverness. At just 22 grams, it is featherlight, yet the blade locks securely for safety in use. Its symmetrical design makes it equally suited for right- or left-handed users, while its slim profile ensures it vanishes into a pocket until needed. Despite its size, the edge endures far longer than ordinary steels, meaning you spend more time using your knife and less time maintaining it.
Some say the U4 resembles a wolf’s tooth—small, sharp, and perfectly adapted for its purpose. And that is perhaps the best description: it is a wolf in sheep’s clothing. Modest to the eye, but carrying within it the precision, strength, and heritage that have made Fallkniven one of the most respected knife makers in the world.
