I finally broke down and made one out of leather because l couldn’t find the right one for me. This way you can customize it to hold what you want and how you want.
Linered will no doubt be tougher but whether or not it's necessary is the question. I don't think dropping it will break it, I'd be more concerned about damaging the blade and tip if dropping it is a real concern.
I have a folding box cutter from husky with a quick release button that's all steel construction. Opens and closes smoothly.
