I just use a couple of screwdrivers myself. I haven't broke down and bought a tool yet. That's mostly because I never remember it until I'm in the middle of a brake job.
After I paid a two shops to do drum brakes (long story), the second shop still fouled it up by either leaving off one of the springs or they did a crap job connecting it and the "nail" fell off instantly, I had to buy the tool. I couldn't get the spring on for anything in the world without it after I got new springs and "nails", so I had to order the Blue Point one. I couldn't find (maybe it wasn't being made at the time) the $10, B10 one. It beats knuckle busting and frustration, or paying a shop who will probably foul up something.
The shop I paid $1200 to do emergency major brake work on the motorhome because I had no tools with me, the rear brake hose, they cut off the old hose, didn't disconnect the axle vent hose from the retaining bolt/vent and remove the bolt for mounting the new hose's metal block to the axle. They just zip tied the new hose to the old one's metal base, still bolted to the axle. Really??? They didn't now how to do that right?
