Attaching a razor-sharp katana sword to the end of a NERF gun certainly qualifies as a dangerous NERF mod. Especially if you’re the kind of person who goes by the screen nic of ADHD. If I’ve learned one thing about sharp objects, it’s always best to pay strict attention to what you’re doing when you’re handling them. Not to be a safety Nazi, but I’m sure impressionable young viewers won’t be inspired by the sword-related horesplay shown in this video. Sigh.
