CRKT Gusset K330KKS – 3.57″ Black Oxide 8Cr13MoV Drop Point, Gusseted Stainless Steel, Frame Lock

CRKT Gusset K330KKS – 3.57" Black Oxide 8Cr13MoV Drop Point Folding Knife

Ken Onion took his inspiration for the CRKT Gusset K330KKS from a dune buggy frame — specifically from the gussets that let a chassis be both stiff and light. Carry that idea into a folding knife and you get the open, skeletonized stainless steel handle that gives this knife its name and its character: seriously engineered to look at, surprisingly light in the pocket, and easy to rinse clean because there is nowhere for grit to hide.

The 3.57" drop point blade is 8Cr13MoV finished in black oxide with CRKT Triple-Point serrations, and it flips open on an IKBS ball bearing pivot into a frame lock. It is an everyday carry with a head-turning design that still does the work — which is why it shows up in searches for a flipper pocket knife, a stainless steel frame lock knife, and a serrated EDC folder alike.

Frequently Asked Questions

Why is the CRKT Gusset K330KKS called a gusset knife?

A gusset is the reinforcing plate that lets a metal frame be stiff without being heavy. Ken Onion borrowed the look from a dune buggy chassis, so the handle of the CRKT Gusset K330KKS is an open, skeletonized stainless steel frame — strength where it is needed, material removed everywhere it is not.

What blade steel is the CRKT Gusset K330KKS?

The CRKT Gusset K330KKS uses 8Cr13MoV stainless hardened to 58–60 HRC with a black oxide finish. It is an easy-going working steel: quick to sharpen, corrosion resistant, and forgiving if the knife spends its life in a pocket rather than a display case.

How do you open the CRKT Gusset K330KKS?

The CRKT Gusset K330KKS is a manual flipper. Press the flipper tab protruding from the spine and the blade rolls open on its IKBS ball bearing pivot, then the frame lock engages behind the tang. There is no assist mechanism — the bearings do the work.

How do you close a frame lock like the CRKT Gusset K330KKS?

Push the lock bar — the cut section of the handle frame itself — sideways with your thumb to clear the blade tang, then fold the blade closed. Because the lock bar on the CRKT Gusset K330KKS is part of the stainless handle, lockup is stiffer and simpler than a separate liner.

Is the CRKT Gusset K330KKS a good EDC knife?

Yes. At 4.0 oz with a 3.57" blade, the CRKT Gusset K330KKS sits in the sweet spot for daily carry, and the deep carry clip keeps it discreet in the pocket. The open handle also makes it one of the easier knives to clean out after messy work.

How do you sharpen the CRKT Gusset K330KKS?

Sharpen the plain forward section of the CRKT Gusset K330KKS on any flat stone at the factory bevel until you raise a burr, then strop it off. For the Triple-Point serrations use a tapered ceramic or diamond rod, working only the ground side of each scallop and finishing the flat back side to remove the burr.
