I am replacing the railings on a deck and plan to use heavy fence wire.
This is a welded wire, galvanized, very heavy guage. It doesn't bend
(much) and comes in 4' x 16' panels rather than rolls.

I need to make a lot of cuts to get smaller pieces to fit into the
railing.

What is the best way to cut this material? One seller recommended bolt
cutters. I suppose I could use a sawzall with a fine-toothed blade but
that sounds laborious. Another friend has recommended an angle
grinder.

What works well?

Why not listen to the guy who sells the material? He's got by far the
best choice listed. You don't say just what gage these panels
are--there are many different ones. If it's what we call "hog panels"
the bolt cutter is really the only practical way. If they're lighter, a
pair of fencing pliers w/ the notch wire cutters work well and are more
nimble.
