Here is one of our favorite bits! This bit is from Herm Sprenger and is a KK in a 5.25", in a thinner diameter, likely a 12 mm, designed for horses who desire less substance to their bit. Many of these older style snaffles are quite weighted. While this one has a nice weight, it isn't as heavy as some. This one is an older style, but the same quality we all love from HS. The link in the middle is longer and rotated by 45°. This bit is specially designed to improve your horse's comfort and performance. In very good used condition, showing very faint teeth marking. **please note, these bits are measured hole to hole, not ring to ring**
