Columbia River Klecker NIRK 3.125" Satin Plain Blade, Brushed Handles

Take two pieces of stainless steel, cut, grind and bend them just right, and you have Glenn Klecker’s "irreducible complexity" NIRK folder from CRKT.

The innovation is Glenn's use of a single sheet of stamped and folded stainless steel to serve as the folder frame, back spacer, spring and lock, resulting in a solid lockback folder. The geometry of the cutout areas is critical, carefully calculated to provide just the right spring action when the rear of the spine is pressed.

At the front of the frame, the lock tab mates with a notch in the blade to provide safe lockup. The tighter the grip on the handle, the tighter the lockup, making this an exceptionally safe design. It is very difficult, if not impossible, to accidentally release the lock, and it is very, very strong.

When the blade is closed, the same lock tab ramps over a rounded detent to hold the blade in the closed position.

The high-carbon stainless steel blade is a utilitarian drop point shape with a deep belly, high hollow ground for easy cutting, and with a swedged top edge to aid penetration. It is a hefty 0.131" thick. The blade can be opened with either hand using the oval thumb hole.


Features

• This lock tab mates with the notch in the blade, resulting in a very strong and safe steelon-steel lockup.
• Press at the base of the spine to release the lock. A camgrind in the blade safely stops the blade at mid-point.
