I've never bent rebar myself so, I can't report on the effort required. I've seen lots of rebar used as tent stakes though so, I know its commonly done. A sturdy vise and proper application of leverage should get the job done. I think a regular hammer would drive rebar into the ground. The "L" gives you a surface on which to facilitate removal. I would recommend that on whatever stakes you use, you cover the expose ends to warn passers by and avoid injuries from careless people walking into them, especially in the dark.

Yeah, I'm always pretty conscious of the safety factor. We have a lot of kids running around when we camp. I try to use brightly colored ropes, but I always worry about the stakes. That's part of why I want to find some valves. You can pound them in completely flush, but not lose them. If I end up with rebar, I'll probably paint the ends so they stand out.
