The term 'FARRIER's Tool' refers to two tools used by farriers, which are professionals who specialize in the care of horses' hooves. The first tool is a RASP, which is a coarse file used to shape and smooth the hoof wall, sole, and frog. The second tool is a froe, which is a tool used to split hooves into layers for easier trimming. Both of these tools are essential for farriers to properly care for horses' hooves.
