Ruike Criterion Collection L31 Multifunction Knife (Black)
Brand: Ruike. The L31 model from the "L" series is a well-designed folding knife for camping and tourism, combining compact dimensions with maximum functionality. The Ruike L31 was created by engineers to fit as many tools as possible into a minimal-sized body: the description states that it has 9 tools "on board," while the model actually provides a wide range of functions, including removable tweezers, a glass breaker at the end of the handle, and other useful elements.
Construction and Materials: The blade and other active tools are made of hardened stainless steel from the Swedish brand Sandvik, steel grade 12C27. The hardness level on the Rockwell scale is 58-59 HRC. The handle is a combination of two metal liners and G10 scales with a textured surface. The scales are available in three colors: black, green, and brown.
Dimensions and Weight: When folded, the knife length is 114 mm; when open, it is 197 mm. The blade length is 85 mm, and the thickness at the spine is 3.0 mm. The blade shape is Drop-point, and the cutting edge grind type is plain. The weight of the folding knife is 166.5 grams.
Locking Mechanism and Features: Most tools, including the blade in both closed and open positions, are secured with a Slip-Joint lock. The design includes removable tweezers, "hidden" in one of the handle scales, as well as a fold-out lanyard hole, a pocket clip, and a corkscrew. The model has a complex design with many utilitarian elements, as well as a glass breaker at the end of the handle.
