Safety.
I am too old, slow, weak, and stupid to use a skil saw anymore.
The band saw is a good idea, but you are stuck.
Sawzall or hand saw. Cutting wheel or angle grinder. No chainsaws
Geesh, I didn't even think to suggest just using a good ole' hacksaw... I'm too accustomed to grabbing the angle grinder or sawzall.
A portable metal band saw might be useful for someone doing rehabs. In my case, I can't justify buying one, as I have no use for it.
