The Rhino Knife is a custom gentleman's folder by SiL Manufactory. The author's Push-up Spring Lock is placed in the knife. The blade is opened with one finger, by the thumb stud, in the style of traditional folders. At the same time, the backspacer acts as a spring that fixes the blade in the working position. There is a lanyard cord hole at the end of the spacer . The blade is released from the lock by pressing on the ricasso of the handle. When closing, the blade goes through two slows down moments, preventing it from falling on the fingers. The thumb stud and hardware are made of titanium. The pocket clip is made of stainless steel. The compact, light weight, spectacular monochrome design plus unusual mechanics make Rhino a great costume knife.
