Customer Reviews

Thoroughly impressed!
BRIAN D. on Apr 20, 2023

Love the look and how it feels in my hand Hits the sweet spot between too big and too small. Almost ZERO blade play! Only OTFs I own that lock up better are my Deadlock model c and SOG Pentagon. My Guardian Tactical & Microtech OTFs feel absolutely sloppy by comparison. My new favorite OTF!
