Reinsman Medium Port Sweet Iron Bit. Very good low leverage bit for horses with a good mouth. Solid cheeks for stability and a medium-severe mouth with a good deal of tongue relief. You will really enjoy watching a well trained, good mouthed horse perform in this moderately light bit. Sweet iron is intended to rust and promotes salivation which makes a more supple feeling mouth. 6” Cheeks • 5” Mouth • 1 1/2” Port • 1/2” Sweet Iron • Medium Port
