Agree 100%. You're not accidentally cutting a rope. If I switch to smaller webbing I may reevaluate, but I've tried sawing on a tether with a Lutz blade and it ain't going nowhere fast.To test this, try taking a broadhead and cutting Samson Predator or even Amsteel blue with one swipe. I know cutting both with a knife is a PITA - I'm worried about slicing a rope. I don't even know how I could get in a position to do so unless I'm less of a monkey than most. My broadhead is usually facing away from my tether.
