Having a martial arts background, Joshua Swanagon has done some training with the karambit and is a fan of ring style knives and their prowess in combative applications. However, also being an avid outdoorsman, he has found them to be less than ideal as field utility blades. So he set out to make a knife that could combine those disciplines and decided to call it the C.U.T. 4.0 (Combat Utility Tool).

It is a combative, ring-knife with a utility style blade for field use. The curved handle and ring of a karambit provide superior comfort during combative use, and a traditional drop point blade profile is ideal in the field. The aggressive tip provides for maximum penetration during combat, allowing the C.U.T. 4.0 to penetrate body armor and heavy clothing much easier while also being useful for drilling chores during fieldcraft tasks.

The C.U.T. 4.0 was designed with professional personnel in mind, but will also make a great EDC for civilians and martial artists who like the diversity of a dual purpose knife.

Joshua Swanagon has studied survival in both urban and wilderness environments in Colorado and Michigan for most of his life while also adding experience in harsher terrains abroad. He utilizes his experience and years of diverse martial arts and combative training and real world application as a self-defense/combatives instructor, published freelance writer and Field Editor for various magazines in the fields of knives, survival, self-defense and tactical subject matters.

Very pleased

Knife is very well made with good fit and finish and sharp edge. Handle is comfortable in either grip for my slightly large hands. Sheath is functional with good retention and a fair amount of adjustment. Powder coating is also well done and durable.

Practically Perfect in Every Way!

Bought this knife for EDC and it's AWESOME! The ONLY problem is that the blade is slightly more than 4" in length measured from the forward finger choil to the blade tip. That's a problem for me because here in Colorado I am limited to a 3.5" blade. I am going to keep this otherwise PERFECT knife because I'm actually going to see if I can find a local guy that will reshape the blade for me and remove that additional .5-ish inches of blade from the tip, thereby making this a perfect - and COLORADO LEGAL - EDC knife... perfect for self-defense!

Yes. Do it.

Really nice knife came sharp. Sheath is very good too. Maybe just a little bit tight but its okay. This handle might not work out for very large hands so make sure you buy where you can return if necessary. Quality is first rate. I would highly recommend this knife and considering the sheath would cost you $50 with the pull the dots so I would say this is a very good value even at its $100+ purchase price.
