His tool eliminates eyeballing, guessing—even measuring—and delivers perfectly straight results. Load the tool with the conveniently stored brads and magnets will hold them in place. Use the built-in level to make sure the tool is straight, then push on the handles to punch the brads into the wall, kind of like a stapler. That’s it—you’re ready to hang photos and artwork, and stand back and admire how nice that wall now looks.
