They are in the sheath, which gives one a false sense of security.
I was holding the sheathed knife in my left hand, with the handle to the right. My left hand was partly on the sheath and partly on the knife handle. Holding it this way doesn't really secure the knife properly.
You are mainly holding the sheath which allows the knife to pop out with the slightest pressure. That pressure comes from trying to pull the paracord tight.
Here's an exercise:
1. Hold the sheathed knife by the handle in your strong hand, pointing straight out, blade side down.
2. Now, take your thumb and press against the rear of the sheath at the top of the knife. Basically trying to push the sheath off.
Pops off pretty easily, didn't it? At least mine does. That's essentially what happens when you try to hold the sheath and handle in one hand while pulling with the other.
And, trust me, I hold no one else responsible for my ignorance. I caused my own injury.
