If you buy one, agree that curved is the way to go. It can do most everything a straight bar can do, and some things straight bar can't do as well. Alternatively, you can probably pick up one of these (5" long) or similar (<$5 in the U.S.), cut to desired length, round the corners off with grinder or file, and drill a lanyard hole. Ergo, homemade mini-prybar for ~29 kr. I've done a few. Works great.
