I was a bit too young to see them in operation, but there were a couple older one armed guys in the neighborhood who got tangle up in them trying to clear a plug.
Dad had one for his little Ford tractor, and the neighbor down the road had a hook he earned by trying to clear a plug. The neighbor was my uncle's coon-hunting buddy. He could shoot his Nylon 66 as well as anyone else, even with just one good arm.
