I have used a bit like this for many years. I have never had a pinching problem using a leather chin strap in the upper rings. I do a lot of trail riding and it seems to keep the horse comfortable but gives me a bit of leverage if needed.
This is a leverage bit not a snaffle.

If you attach reins to the middle rings, it's a snaffle, more or less.
If you attach reins to the bottom rings, it's a curb.
If you attach 2 sets of reins, one to the middle rings, one to the bottom rings, it acts, more or less, like an English pelham and might be used, I guess, in that way as a sort of transition bit, moving from a snaffle to a curb - although I can't say that I've ever seen anyone do that.
