Buck Knives 110 Slim Select 3.75 inch Folding Knife - A new EDC based on American classic, the 110 folding hunter, the 110 slim possesses the same traditional features but sports a more modern look. The deep carry pocket clip is added based on the overwhelming customer demand and allows for quick and easy access in any situation. The 8.625 inch knife folds down to 4.875 when closed for easy carry. With easy one-handed opening, the 420HC stainless steel blade provides supreme edge retention and is finished with Buck's Advanced Edge2x Blade Technology. To decrease the weight and thickness, the heavy bolster and handles are replaced with lightweight molded nylon while still maintaining the same quality and rigidity of the original 110.  

Lockback folding knives have a mechanism that lock the blade in the open position, activated by opening the blade all the way. A lock back gets its name from a rocker (rocking lock bar) partially visible on top of the knife. Opening the blade causes the rocker to lock against the blade so it locks open. Pushing down on the rocker on top of the handle releases it and enables the user to close the blade. Lockbacks require two hand closing, though some are one hand openers.
