Well I'm happy for you, but I find it a bit unlikely that you have removed "many such freewheel bodies" - meaning a notched type with only the center remaining - using a freewheel tool. I worked as a mechanic for over 20 years, and in that time I had relatively few occasions where I had to destructively remove a freewheel, and almost none where only the body remained when it was brought in. The notched style remover depends on the outer ring/cone to hold it centered, so it's risky to use the tool when only the core remains. Besides that, it's silly to do so when it's quicker as well as safer to just put it in the vise.
