The folding knives in the Tre Kronor series are lightweight, safe and beautiful. The edge steel, 3G, is a revolutionary laminated anticorrosive steel, with a core comprising the well-proven powder steel Super Gold Powder Steel (SGPS) and sides of VG2. The size of the folding knives is adapted for active everyday use; and if a larger or stronger knife is needed, we recommend either of our sheath knives TK1 or TK2. TK4 is a workhorse with clean lines that combines lightness with strength. The slim handle in rigid composite material is both lightweight and strong, and completely resistant to corrosion and solvents. With nail nicks in both sides of the blade, the knife is completely symmetrical and as easy to handle for both left-handed and right-handed users. The well-proven locking mechanism fixes the blade securely in its open position.
