WithArmour (not to be confused with Under Armour) is a Chinese manufacturer of fixed-blade knives, folding knives, and outdoor gear such as multitools, flashlights, etc. While largely unknown in Poland, in Russia, its products are distributed by the Moscow-based company NOKS. WithArmour produces very respectable knives, using good materials (primarily 440C, but not limited to), with good build quality, and based on their own original designs. For example, I have never encountered one of their folding knives with a liner lock that fails to engage or with any "blade play." You can find review and testing videos of their products on YouTube. For brand-name knives, they offer an excellent price-to-quality ratio.
