Do you like picking mushrooms? I personally love. But when I pick mushrooms, I often pick mushroom knives. Whatever this happened to me, I made such a suit for the knife. Since then, I have no problems with knives for picking mushrooms.
At any time, you can "throw out" the knife (if it interferes) and then "pick up" with a flick of the wrist. The knife will lie in your open palm.
I hope everything will be clear from the photo. Try it, you will like it.
