There was a maker on here that posted a "custom" box cutter/utility knife combo. Milled micarta handle etc. that screws together to hold the blade very very securely. Riley is the maker. I bought one and love it. Fits in the pocket like nothing is there weighs mere ounce or two and works to perfection for opening boxes etc. So save your blades and buy one and use it. I don't know the guy other than purchasing this one here on the forums last year. I think he has a YouTube channel too. So there ya go. Your welcome. stay safe
