Ruike Criterion Collection S21 Multifunction Knife (Green)

Brand: Ruike. The S21 model from the Criterion Collection is a compact and reliable folding knife designed for camping, hiking, fishing, picnics, and everyday carry (EDC). This knife combines high-quality materials and a well-thought-out design in a small and lightweight body.

The blade is made of 12C27 stainless steel, which has undergone low-temperature hardening and achieved a hardness of approximately 58-59 HRC, ensuring good wear resistance and ease of sharpening. The blade shape is drop-point, smoothly polished, with a sharp tip and a blade length of 53 mm. The blade thickness is 2 mm, providing a balance between strength and cutting precision.

The handle is formed on a steel base with G10 fiberglass scales. The scales have a textured surface for a secure grip in high humidity conditions. Available handle colors: green (this model), black, and brown. On one side, there is a steel clip for pocket attachment, and on the end, a metal ring for a lanyard or keys.

Hidden in the handle is an additional thin steel plate with tools: a small flat-head screwdriver with a 4 mm slot, a strap cutter, and a bottle opener. These tools deploy from the same side as the blade, making the model even more versatile for field and everyday tasks.

Lock and Construction

The model uses a Slip-joint lock, which prevents accidental folding of the knife during use, although it does not provide rigid blade locking. The overall length when closed is 71 mm, and the knife's weight is 43 g, making it convenient for daily carry.
