Beautiful Buck 110 automatic single action conversion- knife has been converted so that when you push the custom brass firing button, the knife opens automatically. This is a single action conversion which means the knife can only be opened by firing the button and can not be opened manually. This knife is gorgeous and features beautiful rosewood handles. The bolsters are brass and complement the handle very well. The conversion quality on these is excellent! Comes with leather sheath and is new in box. These are fully functional knives converted and customized by skilled craftsmen, but we do not recommend them for heavy use.
