How should i think about tpi? is 24 or 32 better for cutting stainless bolts?

This article is informative; http://diyhousehelp.com/tools/choosing-the-correct-hacksaw-blade-tooth-count

How long will one of these blades last on average if you use it an average of once or twice a week for small projects?

Depends on the material. Copper and aluminum are soft metals. The blade is going to last a long time. Stainless steel and harden metals not as long. I use mine on all sorts of different materials and I get at least a year out of each blade.

Starrett green stripe vs Starrett red stripe blades? What is the difference?

I had no clue, so I googled it & this is what I found. Greenstripe® These hardened-milled tooth blades are shatter resistant and are the best blade for interrupted cuts or when the blade is subject to excessive stresses. Redstripe® Constructed of uniformly hardened high speed steel, these blades maintain their cutting edge on the most difficult to cut materials, held securely. Bluestripe® These precision ground tooth blades have a patented solid-state diffusion process which produces the industry's most advanced bi-metal hand hacksaw.

How well would this cut an aluminum hand guard on a paintball marker?

I've cut through steel with these blades. As long as the metal on the hand guard is not thinner than 1/32", and the correct technique is used, there should be no problem.

If you are going to cut Carbon Steerer's or seat posts, make sure to order extras. Carbon is very harsh on these blades and make sure to use fast light movements on the hacksaw handle or else the blade will dull very fast if you go to slow.

Starrett vs Eclipse? I think Eclipse are better; just. Starrett cuts well but chokes easily. The opposite is true for Eclipse in my experience. But overall a great performance when cutting choke inducing thin gauge aluminium.

Lenox and Starrett hacksaw blades are reasonably priced on Amazon and are of more than adequate quality.
