SOG Pent Arc – Badass Knife of the Week

It’s pretty rare to have a blade shape on a knife that bucks the trend of drop point or clip point profiles. But that’s what you get with the latest Badass Knife of the Week.

The SOG Pent Arc is a modern folding knife with a blade inspired by the spear point profiles of the past. This knife is built with a purpose. It is designed to be used by military and law enforcement for defensive carry in hostile or unknown situations.

The 4-inch bead-blasted blade is made from VG-10 stainless steel, an alloy that can be sharpened to a keen edge without becoming brittle. A fuller or blood groove down the middle of either side of the blade completes the look of a classic dagger while helping reduce the overall weight of the knife and increasing its intimidation factor.

With its smooth operation and secure lockup, the Arc-Lock remains one of the easiest to use locking mechanisms on the market. Not only does it allow for true ambidextrous use but it provides easy one-handed opening and closing.

Featuring stainless steel liners and glass-filled nylon scales, the handle is grippy and durable. A deep-carry pocket clip can be changed for left hand or right hand tip-up carry. This makes every aspect of the knife ambidextrous — from the lock to the dual thumb studs.

At an overall weight of 4.4 ounces, the SOG Pent Arc is a strong and quick folder you can carry as EDC or self-defense.


  1. How much do the fullers reduce the blade weight? Two grams? Four grams? Those narrow fullers don’t look intimidating to me..

      Fullers don’t reduce too much weight but if you cut off a few grams here and there, they can add up. They can also be a stylistic choice.
