Okay kiddo, have you ever seen a tool called a pickaxe? It's a tool that's used to dig into the ground and break up rocks. Well, a horseman's pick is kind of like that, but it's made for people who ride horses!
When a horseman is traveling on a trail or path, sometimes they come across obstacles like fallen trees or big rocks that can't be easily ridden around. That's where the horseman's pick comes in. It's a tool that has two parts - a long handle and a pointy end that's kind of like a miniature pickaxe.
The horseman can use the pick to break up big rocks or tree roots that are blocking their path. They can also use it to dig a small trench in the ground to divert water away from the trail. It's a really handy tool to have if you're exploring the great outdoors on horseback.
So, basically, a horseman's pick is a tool that helps horse riders overcome obstacles and make their way safely down a path.
