When I bought my large egg I also bought the ash tool but now notice there are 3 different sizes offered according to their website. Mine didn't come in a package so I don't know if the dealer sold me the right size. What is the difference between them all, is it the size of the bar or the overall length? The bar on mine is 2" and the length is 16.5". Do I have the right one? Also the coiled handle seems to jiggle around, is this normal? And what is the other end used for? Thanx.
