I've tried it with pliers, but you can't be consistent with the bends and your baits won't look that great. What I do is put some angled flat steel in my vise so the serrated jaws of the vise won't mar the finish on my stainless blades. Put them in that vise one at a time where you want your bend. Take a piece of board, I have a piece of oak, and lay it against your blade. Then you whack it with a hammer. Try to drive that board through your blade. You won't hurt anything but it puts a good uniform bend right where you need it. Lather, rinse, repeat, til you get all the blades bent you bought. Won't have to do that again. When your finished, you can stack em all together and there won't be a millimeters difference in them.
