D191 is designed to exceed users' expectation for 8Cr13MoV blade knives. Its blade goes through cryogenic treatment as well as other steels in RUIKE factory so that it assumes better properties. Its handle consists of two types of materials. The G10 front scale is finely textured to be skid-proof while the stainless steel back contributes more reliability to the whole handle structure. Besides being lightweight and comfortable to grip, with a roller bearing washer set inside, D191 also offers smooth blade deployment.
