CR5175: Nirk Novo - Designed by Glenn Klecker
Columbia River
Intelligent design advocate Michael Behe coined the term "irreducible complexity," which means "a single system composed of several wellmatched, interacting parts that contribute to the basic function of the system, wherein the removal of any one of the parts causes the system toeffectively cease functioning." 

It certainly describes this folder line 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-thoughtout 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 new NIRK Novo models are slightly smaller with 2.75" sheepsfoot blades,weight of only 2.5 ounces, a thumb stud for opening, and are available in Razor-Sharp and Combined Razor-Sharp & Triple-Point™ Serrated edge options.There you have it: simple, flat, almost indestructible folders. They are 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. All models have stainless steel pocket/gear clips.

Pros: Lock Type, Overall Quality, Weight, Blade Sharpness, None
Cons: Handle Feel, Lock Ease of Use
Innovative and practical knife
This was a little larger than expected, but I like it a lot. The design is a little different from most other knives. The blade is sharp and seems like good steel. Despite its overall length and height, it's thin and light. This is good to carry in a pocket or bag for cutting or slicing. While I was able to grip the knife well, it just didn't have the feel of a perfect fit in my hand. the lock is at the back, so that I have to shift the knife in my hand to unlock and fold it back after use.

Pros: Overall Quality, Blade Sharpness, Handle Feel, Weight, Ease of Opening, Lock Type
Cons: None
You can't bet it for the price...
I bought this knife to drop in my daypack for just-in-case use, but it turned out to be so handy that it's now often my everyday carry knife. It was sharp out of the box and the serrated part of the blade really goes through heavier material. The security of the lock is excellent.
