Based on Buck's first ever interchangeable blade knife launched in 1990, the 550 Selector 2.0 gets a 21st Century upgrade. Modeled after the Open Season line of hunting knives, the 2.0 features 3 easily interchangeable blades in 1 convenient package. 

The Blades: All three are crafted in the USA from Buck's edge retaining 420HC steel that features Buck's patented heat treat process. This process provides corrosion resistance and an edge that is easily re-sharpened. The standard is a plain edge drop point utility blade style for every day tasks. This one is followed up by the same shape, but with partial serrations that provide greater cutting power through line, rope or cables. The final option is a gutting blade for use when field dressing game. All three are easily opened via an ambidextrous thumb hole oval cutout in the blade. Function has a noticeable stop along the way, but is easily and smoothly overcome. This allows the interchangeable mechanism to perform.

The Handle: Black thermoplastic handle scales with gray aluminum inlays are attached to stonewashed stainless steel creating a solid, ergonomic grip. These scales should fill most medium to large palms comfortably in the field. Internals have skeletonized cutouts to lighten the carry and balance the overall design. A mid-lockback mechanism not only locks the blade in the open position, but doubles as the button that releases the blade from the handle.   

To Change Out Your Blade: Buck made switching a breeze! First, remove the blade you want to use from its provided sheath. Second, open the current installed blade to its half stop. Next, place the provided sheath over the open blade to protect yourself while working. Finally, depress the lockback button on the handle and pull up on the blade. The blade should slide out of the pivot easily making it ready for the blade you need. To install, push down on the lock again and slide the blade into the pivot. 

The 550 Selector 2.0 Folder includes a heavy duty black polyester belt sheath that carries the knife, blades and sheaths.
