I'm new to the hobby, and I'm sorry if this has been coverd alot but I don't know what to call it to look it up. What is this blade texture called, and how is it done? Makeing peices like this is what made me want to try this out.

It's called rock pattern and needs to be grinded in. You can use small wheel attachments on the sander, angle grinder with different disc's and different files to do it. You darken the blade by etching it in a acid, usually ferric chlorid. You can also combine it with stone washing.
 
Ok. Well. It looks kind of like precise hammer work to me. (Edit, freddy cryo is right, it's not hammered, though you can get something kind of similar doing that, look at Japanese kitchen knives to see what I mean) That or filing. You can do it a few ways. A dremel if you're precise enough, or a very small wheel on a 2x72 could work maybe.

Getting that color. I'm not 100% sure. It could be some kind of coating. Although you may be able to kind of pull something similar off buy brushing the steel with a brass (or even better for that color, if you can find it copper) brush. It will leave a gold color on top of the dark scale that forms.

I have a feeling they might have used some kind of coating. I'll look again and edit.

That copper color is what has me wondering how they did that personally.

I have no idea who made that knife, so idk if its something cheap or not, because ifit's cheap, my mind goes to spray paint lol. But if not, idk. Tumbling it in copper?

If you purchase a membership, (I'm not sure if a Basic will work, but I know a Gold membership will) you can upload photos directly from your computer as long as the byte size isn't too large. I rename/copy/change file type to .jpg on my photos to around 100kb at 960 X 720.
 
My guess is that he forges the bevels where he wants it, but leaves the spine short but thick, then grinds in the lines with a cutoff disk as FredyCro FredyCro said, some in a feather-ish sweep up the heel, sometimes letting the thin cutting disc grooves cross, and then forges the spine and tang out, letting the grooves flatten and smush out as they do.
But that's just my guess.

That's how it appears to me, as well.
 
My guess on the copper is thick electroplating followed by chemical tarnishing and a very light polish to bring back the high surfaces. I suppose you could do a copper brushing technique before heat treatment, but you would have to do that after adding the texture and might get patchy coverage. Electroplating would get a more even cover.
