The Bear Grylls Paracord knife is a solid tool that has multiple uses and will last a lifetime.
I love the sheath, it has the ability to be taken apart and have the belt/strap holder moved around on sheath allowing you to put it in almost any position on a belt, backpack or harness. Think mine is going on my wading belt.
It is a little at the heavy size at almost 5oz and I do plan on swapping out the current cord to a different color and I have heard when rewrapping you can add additional inches of cord.
