CJRB Mini Pyrite Button Lock EDC folding pocket knife. Closed knife length 8cm. 6cm AR-RPM9 stainless steel blade with black PDV coating. Aluminum handle. Lanyard hole. Pocket clip. Button lock/unlock system. The CJRB Mini Pyrite folding pocket knife is an elegant folding knife with a slender design. With its button lock system, it's a real pleasure to open and close, and you'll often find yourself using it as a hobby (e.g. when you're on the phone!). The CJRB Mini Pyrite Button Lock EDC pocket knife offers great versatility for everyday use, as well as a good grip. The aluminum handle is particularly elegant and stylish.
