Back by popular demand—Buck’s interchangeable blade knife- to fit all your hunting needs! In 1990, Buck Knives introduced its first interchangeable blade knife with the release of the original Selector. That version, although discontinued, remained a favorite for many Buck users and many have requested that Buck bring this back to the lineup. Buck Knives is excited to offer the new and improved version--the Selector 2.0! Based on the successful Open Season line, the Selector 2.0 currently features three interchangeable blades: drop point, drop point serrated, and gutting. So, whether you need a clean, precision cut, an aggressive cut, or a guthook blade ideal for field dressing, the Buck Knives Selector 2.0 is equipped for the task. Each blade is treated with Buck’s standard 420HC steel and heat treated by Buck's patented heat treat process and the mid-lockback design allows for simple and safe blade change-out. The 420HC steel is great for edge retention and corrosion resistance and is also easily re-sharpened. Proudly made in the USA and always backed by Buck’s Famous Forever Warranty.

Available Features and Options

420HC Steel

This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.

Gut Hook

For great performance when field dressing game, a gut or skinning hook is an ideal tool. We’ve paid careful attention to the angles on the sharpened edge, shape and size of the entry opening and location of the hook on the blade, making a Buck gut hook the best.


Serrations give your Buck blade greater cutting power. Especially useful when cutting line and/or cables.
