Familiarity: I've put it through the wringer
This tool is a little messy and you get cuttings everywhere when you use a hacksaw. Stuff you don't wont mingling with your sanctions and seals. It does do a great job except for the mess and and is very will made.
I have to agree with Scott on using pipe cutters
