Got a 12″ wide x 15′ long roll of .010. I need to cut it up into a few 3.5″ x 15′ long strips and I’d like a nice clean edge.
Should I just use my razor knife and straightedge? Never worked copper this thin before.

Hoping there's something better then tin snips like I've always used before ..
Do the strips really need to be 15'?
If not, then maybe a sheet metal shop with a shear can cut them for you... 10' is a reasonably common shear size, but larger ones exist.
Well, actually 12'4". I usually have my local sheet metal shop cut the heavier copper I've used before.http://www.woodsshop.com
If their shear is set properly, they should be able to cut the thin material no problem.
The only other thing I can think of, other than snips, is a set of double cut shears.
If you need a straight cut, the shop shear is the only way to go.
A sharp razor knife and a guide might work, I have never cut copper using that method.
I've got a gap shear which cuts continuously about 4 1/2 ft at a time. Should be a fairly common item in sheet metal shops.
A slitter would likely ripple metal that thin.

But you all knew that. I detailed it extensively in my blog.
A couple years ago needed to cut a few hundred feet of 3/8" wide 10 mil Cu to wind some specialty transformers.
Best was plain ol' heavy duty scissors - tried everything from computer controlled circuit board cutter to laser cutting, plain ol' scissors worked the best for the fastest and cleanest cut - did not 'cut' with they, pushed the opened scissors along a straight edge with Cu sheet clamped down.
OK, I'll make a test using scissors, and stop by my sheet metal shop and see what they can do. I do need clean straight edges. Appreciate the advise!http://www.woodsshop.com
For scissors, if your initial test works out, stop by a fabric store for a good pair of Swedish (can't remember the brand) or German (Gingher) scissors.
If your view never changes you're following the wrong leader
