RITDRMK5: RSK Mk5 Neck Knife

Doug Ritter Knives

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 website 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 ergonomically curved handle provides a secure and comfortable two-finger grip while a nylon lanyard with cord-lock adds additional length which adjusts to fit your hand.

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 glass-filled nylon sheath and a mint-size carrying tin along with Doug's suggestions for building up your own personal survival kit.

Found in Hong Kong
I found on of these on a sidewalk in Hong Kong about 10 years ago. Brought it back to USA and it’s been in my truck door pocket since then. It’s excellent.

Excellent Little Backup Knife
This knife is great as a backup. It's stout, sturdy, and arrived razor sharp. I 3d printed a belt loop so that I can carry it horizontally on the front of my waist; I feel that's the best way to carry it, at least for me. Overall, great knife.

tiny fixed blade survival knife
Does what it says on the tin (literally--it is packaged in an Altoids-like tin), and the lanyard works well as a handle extension. You can apply considerable pressures on the blade spin with your thumb when you use the lanyard as a grip. The sheath is reasonably secure but might get loose with repeated use. I like that it's a fixed blade so you don't have to worry about gunking up a hinge if you use the knife on something messy. Just wipe it down afterwards. Main drawback is the small size, but that is constrained by having to fit in the altoids tin.
