I don’t trust the MSM to get anything right. A sabre-saw has a fairly small blade and short stroke ... if that’s what they were misusing, it might not be too bad. A reciprocating saw (Sawzall) has a fairly large blade and longer stroke. If that’s what they were misusing ... it’s gonna be ugly.
Im just envisioning what was ‘on and at the end’ of the saw....the saw would have to be sturdy to hold something like that on it....that rubber stuff can be weighty....hahaha! Im just sayin..... ;)
