okay, than I stand corrected... but answer this for me (cause im a little confused, because I was taught it did have levrage and work the poll) does it work the poll at all, and if so how much? And that it does have any or very slight leverage at all like an ordinary Kimberwick, or was I taught wrong on how the this bit actually works? :S
Nope :] It doesn't effect the Poll at all - Because as I said above, in order for the bit to pull down on the poll, it needs to have the reins attaching at a point lower than the mouthpiece itself. To really effect the poll it also needs a curb strap. A kimberwick without slots only has a very mild curb action - in fact hardly any, and it works very similar to a baucher. A kimberwick with slots , where you can fix your reins lower then the mouthpiece, is the much more effective leverage bit - Because you can only start rotating the mouthpiece when that happens.
And the "d" ring with hooks, if it acts like a mild gag, than why is it still considered a snaffle - cause that's what I was told. Or is this another perfect example of people using bits, and not really knowing how they work or what they actually do in the horses mouth?
Not so much of people not knowing how they work - More like not knowing/bothering to use the correct terminology for the action of the bit. Most people think a snaffle is anything with a broken mouthpiece, when it fact a snaffle can have any mouthpiece you like. This bit can also be used as a perfectly normal snaffle if you don't use the hooks.
and what would be the ratio for a plan snaffle is it 1:1? Than what about the "D" ring with hooks whats that ratio? And how do you actually determine this ratio?
Yep, plain snaffle is 1:1. I have no idea how they work out the other ratios, it's do with the length of the purchase, shanks, and wether there is a curb chain. Too math-sy for me! But the D ring with hooks would be 1:1 when the hooks aren't used, and slightly (Only slightly) more when they are being used.
