I have several saws, both pneumatic and electric that use relatively 
high speed cutting abrasive disks, including a cut-off saw that were 
designed specifically for cutting metal.  You use the proper safety 
equipment which includes a full face shield meant for this kind of work, 
leather gloves, knowledge of the the equipment and how to properly use 
it,  and usually a leather shop apron and don't forget a shirt or jacket 
with long sleeves made of a rather durable material and not a thin 

Like an Oxy Acetylene cutting torch it takes knowing how to use the 
equipment and practice so you know what to expect if a blade or wheel 

My preference for this type of work is the small, air powered, cut off 
saw that uses about a 3" diameter, high speed, relatively thin abrasive 
disk.  I even use a small one with a true rotating saw blade for 
slotting tubing.  Now there is something that can grab and you do not 
want any body parts in the direction that sicker is going to jump. Also 
if it jumps you are probably going to be starting over on slotting what 
is now a bit shorter piece of tube.

I have to plead guilty to not liking a saws-all. It's just too much 
weight and too big to easily handle when up the side of a tower.
