Not a stupid question at all. Yes, the head of the saw rests on the rim of the scabbard. Often the dogs chew it up a little to make a sort of form fit. There is very little flex force on the bar as long as the scabbard is long enough to go up to the head or at least close. It's a common tried and true method of carrying a saw.

Thanks for that input. I guess I need to revert back to the head resting on the top rim of the scabbard. Right now, it's intentionally not because I was afraid of bending the spikes.
