If locksmithing tools are outlawed, then only outlaws will have locksmithing tools.
From that perspective, the ban makes sense, kind of. If the police catch a burglar with locksmithing tools, then he's automatically a criminal, even if they can't prove he broke into anybody's houses. What if he's not a burglar? Well, law-abiding citizens by definition wouldn't have those tools, unless they have the appropriate certification, which the police can of course check.
It serves as a convenient filter to lower the bar to being able to arrest burglars. Of course, there's the question of whether there are legitimate reasons for non-certified people to have these tools, and whether the tradeoff is worth it (I'd certainly lean toward "no" there, since it seems like a big restriction of freedom for a minor gain), but on its face the prohibition is not completely absurd.
