I am looking for a thingamajig that you press into the ground and place your high tensil wire on so you can pull it without unraveling the whole thing. The one fella at the farm supply called it a "spinning jenny". Is that it? Everyone I have asked since looks at me like I'm wearing a ski mask in June. Can any one help with the right name? And where can I find one. I want to get started on my fence and feel I should have one of these doohickies. Thanks.
