I have been continually learning from my Papa (grandpa) since I was just a runt and my choice of tool is approx. 4' X 1" wooden handle like off of a broom or hoe. Don't use it really just have it in case because you never know.
I am new here I like what I have heard though and why I am commenting I'm young and trying to learn as much as possible so Iplease take it easy on me but my Grandpa and I have been using the purina mineral tub for the last year or so now and I would have to say it has had a very positive effect...
