Sog Pentagon Xr 3.6" Blackout

The SOG Pentagon XR 3.6" Blackout folding knife is engineered for mechanics, technicians, and field professionals who demand a compact, reliable cutting tool for workshop and mobile tasks. Whether you're opening packaging on job sites, cutting through safety seals, or performing precision work under vehicles, this knife delivers the control and durability required in demanding environments.

The blackout finish eliminates reflective surfaces, making it equally suited to low-light automotive work or tactical applications where visibility matters. Built with SOG's proven Pentagon blade geometry, the blade length of 3.6 inches provides optimal length-to-weight balance for sustained cutting without hand fatigue during extended use. The folding mechanism locks securely into open and closed positions, preventing accidental blade closure during operation—critical when working around moving parts or in positions where both hands are engaged.

Mechanics, restoration technicians, and mobile service professionals benefit most from this knife's closed length of 11 inches, which tucks easily into tool bags, engine compartments, or cargo pockets without bulk. At 0.56 pounds, it adds negligible weight to your kit while remaining substantial enough for sustained cutting tasks. The ergonomic handle geometry ensures a positive grip even with work gloves or oil-covered hands, a necessity in automotive shops where slip hazards are constant concerns.
