Ruko Knives Shark Features The Ruko Knives Shark carries a 4 inch blade machined from 420A steel a stainless alloy chosen for reasonable edge retention combined with good corrosion resistance for everyday carry use. A hardness rating of 48 to 50 keeps the blade tough enough for daily tasks while remaining easy to touch up on a stone or strop. The assisted opening mechanism snaps the blade into place with minimal manual effort once the opening motion begins giving the user fast confident deployment with one hand. This makes the knife practical for situations where quick access matters. The handle is built from acrylic finished in a striking White Pearl color giving the Shark a refined collectible appearance that distinguishes it from standard tactical-styled folders. At 5.76 ounces the knife carries enough heft to feel substantial without becoming a burden in a pocket. The knife ships boxed making it a presentable option for gifting or display as well as daily use. For anyone wanting a folding knife that combines everyday utility with a unique look the Ruko Shark fits the role well.
