Lee Lerman Custom Knives bolster lock Hydra #15 featuring a belt satin finished persian style blade riding on bearings, fine eggshell finished titanium bolsters/frames, and beautifully finished zirconium scales pivot rings and floating backspacer. Lee is most definitely at the top of his knife making game at the mind-blowing age of only 28 and I consider his knives to be some the best available. The actions are lightning fast and silky smooth, the fit and finish is second to none, and the attention to detail might be unmatched. (Note a small scuff on the clip side of the blade that was there when I purchased the knife.) Knife is preowned but in good condition.
