This is one of four lockback interframe folders in this style that Billy made out of titanium. He gave up after that since the titanium was too hard on his tools. The knife is 5 3/4" open, 3 3/8" closed, and has a mirror finished 2 3/8" blade of 440-C stainless steel. The interframe inlays are premium black lip mother of pearl. The frame is a very fine satin finish inside and out, and perhaps the most unique feature on the knife is the flush lockback release. This is a flawlessly finished folder, and rock solid as well.
