I used old fine toothed  7 1/4" skilsaw with the blade reversed.  Made a
good "endless" file!  Cut halfway through and break.

Folling this line of thought, try a "chop saw". They are available at Lowes,

Home Depot, and most hardware store at a fairly reasonable cost.  Keep in 
mind the size one can cut goes down in a hurry when cutting at an angle. 
Mine has a 12 or 14" wheel.  In 3 to 5 seconds it'll cut all the way through

a piece of 1/2" rebar.  A few seconds more for 1 to 2" steel angle. It'll do

3" steel pipe in 10 seconds.

OTOH you do need to be careful about the stream of sparks coming off the 
thing.  They are more than just a shower of sparks.  When it goes through 
that much metal that fast there is a *lot* of heat given off in that stream.

The ends of the rod will be glowing cherry red.

I have a dust collection system in my shop which works very well.  I was 
cutting 1" square steel tube with a 1/8" wall.  There is about 30 feet of 5"

flex hose going to the manifold.  After about the 5 th cut I noticed the 
first three feet of hose didn't look all that great.  It didn't catch fire 
and the sparks were cool by the time they got back to the collector, but 
little was left of that first three feet except the spring steel wire that 
gave the hose its shape.  it did do a good job of keeping all the crud off 
the floor though.  Chop saws make a real mess!
Outdoors you'd need to keep it away from dry grass, leaves, and paper.
