CR2380: RSK Mk5™
Columbia River


Sometimes simple is better. Here is a skeletonized fixed blade designed as a personal carry for emergency and survival use.

Doug Ritter's RSK Mk5™ (Ritter Survival Knife) is not a knife you would use all day for normal work tasks. But, based on Doug's philosophy that "if it isn't with you, it can't save you™," it is compact and light enough to fit in almost any small personal survival kit or stash-away location, yet robust enough that it's a knife you can bet your life on™.

Doug is the founder of the Equipped To Survive™ and an international authority on survival equipment. The RSK Mk5 is a collaborative effort based on Georgia knifemaker David White's custom Shrewd Survival Knife, itself the result of collaboration with Dr. Andrew Osbourne.

Weighing in at less than an ounce, the skeletonized fixed blade sports a 1.75" wide-chord drop-point blade with a high flat grind. The high-carbon steel blade has Doug's preferred stonewashed finish for improved corrosion resistance.

The ergonomic curved handle provides a secure and comfortable two-finger grip while a brightly colored nylon cord fob adds additional length and grip.

Use it to make fuzz sticks, construct shelter, gut a fish, dress game or for self-defense. Whether it is wilderness or urban survival, the Mk5 will do its part to keep you alive and kicking.

Includes a custom-fitted Kydex® sheath and a mint-size carrying tin along with Doug's suggestions for building up your own personal survival kit.

About Doug Ritter
Doug Ritter
is an internationally acknowledged authority on survival equipment. He founded and publishes the renowned Equipped To Survive and is Chairman of the non-profit Equipped To Survive Foundation. Doug doesn't claim to be a knifemaker, but he is not shy about promoting the practical design features that he prefers to see in a functional survival tool. In the past few years that has evolved into successful limited production collaborations with a number of makers incorporating his functional knife design philosophy and an eye for simple, practical and beautiful blade design. Doug's aim is to maximize functionality and minimize all else, "everything you need, nothing you don't™," as he puts it. The compact RSK Mk5 is his first CRKT collaboration and the first to be distributed widely through normal knife sales channels. Columbia River Knife & Tool is extremely happy to have an expert on personal and outdoor survival on board, and we hope to find other outlets for Doug's specialized expertise.

Pros: Sheath/Scabbard, Blade Sharpness, Overall Quality, Weight, Blade Material, None
Cons: Handle Material
Great edge and holds it well.
Had to add a paracord lanyard for a better grip but it's very light and useful as a neck knife. I was going to keep it in a small kit but I've ended up wearing on any outdoor event.

Pros: Weight, Blade Material, Sheath/Scabbard
Cons: None
Have it with me every day
I bought it for the size and it was one piece or steel. I don't have to worry about the blade coming out of the handle. It's not terribly easy to manipulate, although I haven't used it for much, but that's the trade off for the size. The lanyard makes a big difference; I had gotten another small knife with a lanyard and at first thought it was just decoration. It's amazing how just something hanging off the bottom can make a difference with these small handles. It rides on a bead-chain very easily, there if you need it, doesn't weigh you down if you don't.
