I have always ridden english disciplines, and was taught that a snaffle bit is, generally, any bit without a leverage component with any mouthpiece, and a curb bit is any bit that includes a leverage component, again with any mouthpiece.
I was speaking to an older gentleman the other day who rides western, and I suggested that his horse may go better in a snaffle as opposed to the long-shanked curb he had him in, since the horse seemed to have a very sensitive mouth and tended to get light up front. (that’s a whole 'nother can of worms…) The gentleman said, “Oh but I do ride him in a snaffle! See? A snaffle.” and showed me the bit, which was a long-shanked curb with a jointed mouthpiece. His understanding seemed to be that anything with a jointed mouthpiece was a “snaffle” and only bits with straight or ported mouthpieces were curbs, regardless of leverage. He also seemed to think that a straight or ported mouthpiece was more ‘severe’.
I thought this was just a singular misunderstanding, but then I saw the same terminology used in a catalog that sold western tack that I was flipping through this morning.
Is this a thing?! Do western riders really talk about bits that way?! If so, how is a REAL snaffle differentiated from a “curb with jointed mouthpiece snaffle” ?
