Ruike Criterion Collection S21 Black Multifunction Knife
Introducing the Ruike Criterion Collection S21 multifunction knife from the Ruike brand, designed for camping and tourism. This model is ideal for hiking, fishing, picnics, and everyday carry (EDC). The knife combines compactness and broad functionality thanks to its thoughtful design and quality materials.
Materials: The blade and additional tools are made of 12C27 stainless steel, and the handle scales are made of G10 fiberglass. The 12C27 steel has undergone cryogenic hardening and achieves a hardness of approximately 58-59 HRC, ensuring long-lasting sharpness retention and easy resharpening. The G10 handle has an uneven outer texture for a secure grip even in wet conditions.
Construction and Lock
The Ruike S21 model uses a Slip-joint lock, which prevents accidental blade folding, although it does not provide rigid fixation in the open position. An additional steel plate with tools is hidden inside the handle, extending from the same side as the blade. A metal ring for keys or a lanyard is located at the end of the handle, and a steel clip is attached to one side for securing the knife in a pocket.
Blade Shape and Parameters
The blade shape is drop-point, ensuring versatility for various tasks: cutting, trimming, piercing. The edge is evenly ground and well-sharpened. Knife parameters: closed length — 71 mm, blade length — 53 mm, blade thickness — 2 mm. The model weighs 43 grams, making it light and convenient for everyday carry.
