Take two pieces of stainless steel, cut, grind and bend them just right,

and you have Glenn Klecker’s new “irreducible complexity” NIRK™

folder from CRKT.

Intelligent design advocate Michael Behe coined the term “irreducible complexity,”

which means “a single system composed of several well-matched, interacting parts that

contribute to the basic function of the system, wherein the removal of any one of the parts

causes the system to effectively cease functioning.”

It certainly describes this new Columbia River Knife & Tool® (CRKT®) folder by

Glenn Klecker, award-winning knife and tool designer from Silverton, Oregon. He has

named it after his son: Nathan’s IRreducible complexity Knife, or NIRK™. There are just

two well-thought out pieces, plus a blade pivot screw.

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


Two NIRK models are available. The 5180 sport and work model has a high satin blade

finish, brushed frame and Razor-Sharp cutting edge. The 5185 tactical model receives a

black oxide nonreflective coating, and has a Combined Razor-Sharp & Triple-Point™

Serrated edge. Both models have a stainless steel pocket/gear clip.

There you have it: a simple, flat, almost indestructible folder. All you need to do is oil

and sharpen it occasionally and you have a friend for life. It is priced so you can afford

several: one for the toolbox, one for the backpack, one for the truck, one for the boat, one

for the survival kit. The satin finished model 5180 has an MSRP of only $24.99, while

the black finished model 5185 is just $29.99 MSRP.

In the knife world, it is a fine example of intelligent design.
