Dutton D Ring Square Mouth Twist

Dutton Offset D-Ring 

Twisted Square Mouth D-Ring Snaffle. Medium to strong severity. 3/8 square bar with copper inlay and Mullen relief. The edges of the square make the bit more aggressive with internal bar pressure, and the twist applies the pressure in a serrated fashion across the bars (pressure, gap, pressure, gap) allowing more feel with less pressure.
