These days, Doug Ritter is best known for founding Knife Rights and fighting for the rights of knife enthusiasts around the country. But, as our latest Badass Knife of the Week reminds us, Ritter isn’t just some guy in a suit; he’s a survival expert that knows a thing or two about what to look for in a good knife.

When you think of the typical survival knife, you probably envision a massive fixed blade with sawback serrations and a hollow handle to conceal a few basic things. The CRKT RSK Mk 5 skips all the fads of modern survival knives and fits everything you need in a compact design that weighs less than an ounce.

Standing for the Ritter Survival Knife, the RSK Mk 5 has an overall length of 3.81 inches with a 1.75-inch blade and skeletonized handle made from stonewashed 2Cr13 steel.

If you think a knife this small can’t help in a survival situation, think again.

Ritter is an internationally recognized authority on survival preparedness as the founder of Equipped To Survive. He subscribes to the philosophy that “if it isn’t with you, it can’t save you” and made a knife that can fit inside a survival tin that goes wherever you go. That philosophy comes to life in this collaboration with custom knifemaker David White.

Although minuscule in size, the knife is robust enough to tackle everyday tasks as a lightweight fixed blade EDC option or neck knife. The handle has a two-finger purchase but the black nylon lanyard adds some length to your grip.

To make this knife easy to carry, CRKT added two options: a custom-fitted glass-filled nylon sheath and a carrying tin. It comes with suggestions on what to put inside the mint-sized tin for the ultimate survival kit.
