Elite Outfitting Solutions Inc. (EOS) has upgraded their popular Trident model with a latch and a ball-bearing pivot. The addition of the latch allows safer carry and keeps the knife in the position of your choice, and the ball-bearing pivot eliminates blade play without damaging the knife's smooth, free-swinging action. The rest of the knife is as it was, with expertly machined handle scales, an eye-catching aesthetic, and unyielding EOS quality. There are balisong collections with and without an EOS Trident, but the latter is superior.

EOS butterfly knives are high-quality, no-nonsense, American-made flippers with standout designs. Shop our selection and pick out your favorite!

Customer Reviews

Not even worth half
Ethan D. on Jul 6, 2022

The blade came dull out of the box. Pivots were tight with no oil. After 5 minutes of flipping, the knife had tons of play. You can hear the handles slapping minutes after flipping and readjusting the handles. My Kershaw Lucha holds up way better and generally feels smoother. This knife isn't even worth half. Only looks good, but is terrible at flipping or EDC.
