To use a grooming tool such as a shedding blade, you need to grip it with both hands or wrap the blade in a loop that you can use one-handed. Then you gently run it through the horse's coat and remove loose hair. The most common mistake people make when using a horse shedder is trying to cut too deeply. This can cause damage to the horse's skin and hair follicles. If you accidentally cut a horse, stop immediately and take the blade out of the horse's hair. Another important thing to remember when using a shedding blade is to avoid hitting any bony parts as this could cause serious injury.
