how to form these crisp lines with hand tools
I'd like to do some shapes like you see in these pictures. How might a person hold those nice crisp lines (circled) using simple hand tools? It could be a seam but I'm not sure, it might just be a bend? Hammer on the inside and dolly on the outside would be guess but looking for advice on how you might go after it.

I'm sure there a many more examples, but, IIRC, if you go through Gojeep's project, you'll see him using chisels for just this purpose.
FWIW

Maybe I'm not so good at the search engine but I get nothing when I use "incise chisel line" and I get overwhelmed when I put in "chisel line". With that search the first 3 threads that come up total over 200 pages of information to sift through. Any body know of any helpful threads?

I used a chisel on my cowl plenum air cleaner project, http://www.allmetalshaping.com/showthread.php?t=18299 both to clean up the hammer formed details and to form the outermost bead on the lid. Thought the thread pics showed more of this detail, but they didn't. I also did the same on a large aluminum leaf that served as armature for a bronze casting. No bead roller here so I had no other means to do lines like that.
The way I eventually did it was to draw a thin line to follow on the metal with a sharpie, then use a chisel that was both rounded very evenly on the edge (where normally sharpened) so it would not gouge or cut the metal & rounded on the corners to start the line. I've got a old masonry hammer with a dressed cross pein head (see it in the above head) that I used as well. For the leaf, I played with how straight or curved the edge was so I could work the lines in evenly. Tried it over a shot bag and then a few other things to make sharper definition. Biggest fail that's hard to avoid is hitting too hard and scarring the metal with an edge or corner of your chisel or corking tool. Hard to clean the up down in the groove. A hard wood tool would probably work fine, just harder to make it as thin as a metal tool. It isn't hard or complicated, just kind of fiddly to produce an even line that's a consistent crease, not a sketchy line of smile-shaped curves.

Incised / chiseled lines in metalwork
Here is an old example of using some sort of "chisel" tool whacked by a hammer, to incise lines in a metal figurine.
https://www.metmuseum.org/art/collection/search/309944 Dram the lines and follow them by tap-tap-tap-tapping the chisel tool onto the metal shaped body / tank / thingamajig. The metal body needs to be annealed along the lines and then re-marked. Pitch can be used to fill the inside, hardened up, and then it becomes the "anvil" against which the metal is driven -TAP-Tap-Thunk-thunk-whack-whack-bappitty-bap. The hammered lines are then dressed with a fine file, and then sanded with 320 grit, and is then buffed out, for polished work. Y'all should just give it a few blisters' worth of your time, Sandmanred. Dividends of deep understanding would then be your prize.
