SIG Sauer K320 Series FAQ

The SIG Sauer K320 series, manufactured by Hogue, blends tactical utility with exceptional American-made craftsmanship. Available in various handle materials, blade shapes, and lock configurations, these folding knives are built for reliable performance.

What pocket clip options does the SIG Sauer K320 offer?
The K320 comes equipped with a four-position deep-carry pocket clip that supports both tip-up and tip-down carry for left- or right-handed users. This is an unusual feature for a crossbar-style lock, which rarely offers a tip-down configuration. Milled louvers on the handle also provide extra traction when drawing the knife from your pocket.
What is the benefit of the K320 using washers in the pivot?
The SIG Sauer K320 pivot operates on washers rather than ball bearings, which prevents dust, dirt, and grit from entering and jamming the pivot mechanism. This design ensures a highly reliable, buttery smooth action even when used in harsh or dirty environments.
How do the handle materials on the K320 affect its balance?
The choice of handle material significantly influences the overall weight distribution of the K320. While synthetic polymer handle versions can feel slightly blade-heavy, the milled aluminum handle variants distribute the weight more evenly to provide a well-balanced and satisfying feel in the hand.
What blade shapes are available in the SIG K320 series?
The K320 series offers both drop point and tanto blade profiles, each measuring 3.5 inches in length. The drop point profile features a slightly higher geometry, offering enhanced slicing performance compared to the tanto profile.
How easy is it to open the SIG Sauer K320?
The manual K320 features a thumb hole opening that works best with a deliberate thumb push or a reverse finger flick. Because the knife utilizes Hogue's ABLE lock, you can also simply pull back on the lock bar to swing the blade open or closed quickly without using the thumb hole.
How are the ergonomics and grip on the SIG K320?
The K320 handle is shaped to fill the hand comfortably for a secure, full grip. It also features a forward finger choil that allows you to choke up for precise cutting tasks, complete with a protective guard nub that prevents your finger from slipping onto the sharpened edge.
