Dang ! is Gene still alive ? . I drove by his shop on the old highway last Saturday and was thinking about him .
Yes, I love dead blow hammers (? mallets ?) and bought one way back when only the Snap On tool truck had them, wow was it ever an expen$ive tool but well worth every penny .
Previously (and truth be told, still in one of my rollaways) I had / have brass , lead and copper hammers to do essentially the same thing.....
What's the deal with your ankles ? mine are weak some how and for the first 1/2 of my life would occasionally flop over sideways crashing me to the ground and causing weeks / months of pain .
I learned to simply fold my knees the *instant* I felt one flopping over, this allows me to crash to the ground rolling on my leg and hip, messy and embarrassing but far less pain .
Beware of steroids ! my buddy got them in his knees for many years then his knees turned to jelly and he had to wear external metal joints the rest of his pain filled life =8-( .
