Large Blade

The main blade of the RUIKE multi-function knives have enhanced thickness and width, providing greater durability and blade capability compared to the competition.

Sandvik 12C27 Blade Material

RUIKE knives are made from Sandvik 12C27 stainless steel. Outside of superior corrosion resistance, the steel provides the blades with added strength, giving the blades tthe ability to retain sharpness for longer.

G10 Knife Handle

RUIKE knife handles are a blend of fiberglass and resin, giving the knives the ability to withstand intense forces, preventing scrapes and general abrasion.

Pocket Clip Design

Given that most owners of knives typically use them within environments that promote wear and tear, RUIKE has created stainless steel clips to holster the knives to protect them during non-use.  Easy to carry, you can be assured that your RUIKE knife is protected.

Tungsten Steel Breaking Cone

Providing added capability, RUIKE knives come with a tungsten steel breaking cone, allowing users to break glass and other tough materials that they may encounter.
