I felt that it was time to finally replace the previously reviewed and loved Kershaw Skyline. The Blade profile was getting bad from early bad attempts at sharpening it. I had accidentally introduced a funky re-curve line in it. Secondly I felt like I wanted a blade that would be a bit bigger and be better suited for self defense. I had mainly narrowed my search down the the Spyderco line of knives. I finally made a decision, with the Spyderco Tenacious, and a purchase and have been testing it for the past week or so. I may revisit this knife after I really put the Tenacious through it’s paces.
