"Sharp Chisels"

Simon AKA "Sharp Chisels" Smith

Simon warming up and tweaking the settings on the Chain Mortiser, I'm led to believe its one of those must have tools.
Hmmm, yes a bit like a woman and her cherry coloured Kenwood Chef! 
What would I know other than that it makes a big noise and a whole lot of mess, but then isn't that the point with power tools?
