The Christensen Knifeworks designed Critical folder is a bold collaboration with Kizer Cutlery. It offers an all-business wharncliffe blade made from CPM-S35VN stainless steel with a thick swedge and ample jimping. The ergonomic titanium frame lock handle is designed with a row of circular cutouts to ensure the Critical won't weigh you down. Anodized pivot collars, a blue anodized titanium backspacer, and a familiar titanium pocket clip have been added for a bit of custom flair.

  • CPM-S35VN blade steel provides outstanding strength, edge retention, and corrosion resistance.
  • Slim titanium handles offer a durable, high performance grip, that is comfortable in the hand or pocket.
  • Blade flipper for rapid blade deployment with a ceramic bearing pivot.

Very good
Shawn K.
Personally I prefer a slightly stronger detent but this thing glides open with ease so it still works, just doesn't feel so great.

The handle design is slightly off for my hands but not a deal breaker. The pointy part at the back might be annoying if you have larger hands where the knife fits fully in your palm.

The overall look is a little more plain in person than on the website, the blade in particular lacked some of the depth the site photos seem to show it as having. Still the blade is probably the high point visually.

If it had a stronger detent I'd probably give a 5, its just so soft I don't feel totally confident on getting it open.

It's an imperfect but still a nicely made $200 knife.

Great knife for the cash.

I've had this knife for a total of three days and I can't put it down. Came in some really nice packaging and was shaving sharp out of the box. Fit and finish are top notch with the only exception being the anodizing on the back spacer has already started to wear through. Lockup is nice and early with zero blade play. Not a bad blade for the money and if you are a fan of Christiansan knifes but can't get one this is a nice alternative.
