Trimming a horse's hooves in the Nicaragua mountains

Here's a quick one for you. One day we went riding on the dirt roads in the mountains of Nicaragua.  But before we headed out, one of the men at Finca Neblina del Bosque kneeled down in front of one of the horses to give it a pedicure.  I put my hand down in front of the horseman.

He looked at me with some puzzlement for a few seconds but then he understood and smiled. However, he knew I didn't really want him to trim my fingernails with a hammer and a machete.
