This utility knife, pocket knife, is one of the slimmest and smallest flipper utility knives ever put into production. The knife handle and various hardware is also made with real 6Al-4V titanium which gives this EDC tool an ultra lightweight feel unlike anything you’ve experienced before as a utility knife. Not only is it super lightweight, but the durability of the titanium handle is built to last! The full double clad ball bearing design also enables this knife to be tightened to near zero tolerances without ANY blade twist from the handle to the razor blade holding mechanism. Unlike other utility knives and razor blade knive tools, this knife holds the blade far more secure than your average utility knife. We took out anything that would fail, this includes any quick-release mechanisms etc. These are prone to fail after many uses, so we went back to the basics with a simple hardened stainless clasped blade-holding design that allows for easy blade replacement without any unscrewing of the clasp. It's also easily swapped out with the press of the right side of the blade clasp to easily switch your blade. RAZOR BLADE FITMENT — This knife fits most razor blades, however to keep tolerances high and low blade-slop, we've designed this knife to work well with the average razor blade.
