Used them a couple of times now for my knife. While a bit difficult to get strapped up, it is because the buckle portion is so positive...I suspect that even if the excess of the strap came loose, it wouldn't allow the strap to come completely undone, which is great.
Make sure you buy the number you need though...picture shows two, for the price you only get one.
