I'm learning basics and I have a collection of a lot of copper wires that are hard to twist. I see now that there is a wire twisting tool out there that exists. I will look into that. However I know I've seen wires that are comprised of very thin conductive wires that are EASY to twist. This will be more convenient for some situations.
What are those easily twisted wires called? They look frayed sometimes.
I Think you're talking about [u]stranded wire[/u]. Stranded wire is more common in electronics. Solid wire is common in house wiring.
Perhaps you mean 30 AWG wirewrap wire?

Stranded! That's what I need. Thanks.

What do you mean by "hard to twist"?
What gauge is the wire and how many strands?
Can you post a picture of the wire please?
Thanks.. Tom.. 
Are you referring to something like this?
