For the blade, Ruike chose 8Cr13MoV steel, a reliable steel that is quick and easy to sharpen. Handy for people who use their knife day in and day out. Not only is the steel type highly practical, but the blade is good too! For the D191-B, Ruike used a drop point blade shape with a high full-flat grind. It's an ideal combination for everyday cutting tasks, like opening boxes or handling cardboard. This pocket knife is easy to open with the flipper, and a sturdy steel frame lock then holds the blade in place.

The handle has a textured G10 handle shell to ensure a good grip. Ruike has added diagonal lines that are not just decorative, but also provide extra grip. Your index finger fits comfortably in the finger groove. The ridges on top of the blade are for your thumb during use. Together, the finger groove and ridges ensure that the knife can't just slip out of your hand while you are cutting.

Specifications:

 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.
