Kubey Flash KU158M Tiffany Blue Linerlock Folder – San Mai M2 Reverse Tanto EDC & Outdoor Knife with Textured G10 Handles & Ceramic Bearings
If you want a standout everyday and outdoor folding knife that merges layered premium steel, smooth bearing action and eye-catching bright styling, the Kubey Flash KU158M Linerlock delivers impressive all-around performance. Developed fully by Kubey Knife’s in-house design team, this ambidextrous utility folder balances rugged cutting capability and lightweight pocket portability, backed by a full lifetime manufacturer warranty for complete peace of mind.
Its centerpiece is a 3.85-inch reverse tanto blade crafted from premium San Mai M2 layered steel. After rigorous vacuum and cryogenic heat treatment, the blade reaches HRC 60–62 hardness, offering fantastic edge retention and reliable cutting power for camping prep, trail maintenance and routine EDC slicing work. Built with a hollow ground plain edge sharpened at a 15°–20° angle, the satin blade finish creates a clean reflective surface that showcases the distinct layered San Mai steel structure. At only 0.12 inches thick, the blade maintains rigidity without sacrificing slicing agility.
The handle uses textured Tiffany blue G10 composite material, delivering secure non-slip grip in wet, dry or gloved conditions. A robust sandblasted stainless steel liner lock holds the blade firmly open during heavy use, eliminating dangerous blade play. Caged ceramic ball bearings at the pivot allow buttery-smooth one-handed opening for both left and right-handed users, perfectly matching its fully ambidextrous layout.
Every metal fitting including the pocket clip, pivot cap, liner and screws is stainless steel with uniform sandblast finishing, forming a sleek silver contrast against the vivid turquoise handle scales. The reversible tip-up clip supports left or right pocket carry, letting users customize their carry setup freely. Weighing 4.48 oz (127 g) with a total 8.50-inch overall length, the Kubey Flash KU158M offers generous blade size without excessive bulk.
Combining unique San Mai M2 metallurgy, hollow grind cutting efficiency, bright Tiffany blue G10 aesthetics and dependable liner lock functionality, the Kubey Flash KU158M is a versatile head-turning folder equally suited for urban daily carry and backcountry outdoor adventures.
