Trevor Burger Sierra

The Trevor Burger Sierra is a larger, custom-built tactical flipper, designed and made entirely in-house by Trevor Burger. Inspired by tactical sketches of the LEXK, it evolved into the original Sierra model. With a snappy action when opening, the Sierra is a great EDC knife for those seeking a larger blade with a slim profile.
