Growing up, I had a serious Jones for martial arts flicks, especially Bruce Lee movies. I also loved to watch anything with a Ninja on the box cover because Ninjas are awesome. One thing I liked about these guys is that they could whip out a grappling hook and climb over anything. I tried to make a grappling hook out of some twine and an old rusty rake head growing up. It nearly worked, which is to say it let loose after I was a few feet off the ground.
What I needed was the Retreev Compact Grappling Tool.
It’s not made specifically for Ninja use, but I know a ninja tool when I see it. The keychain size hook comes with aluminum and stainless steel spikes and has a magnetic head for grabbing metal items. Sadly, it’s not strong enough for actually holding your weight unless you’re Ant-Man, but it should wonders to get back that Frisbee that landed on the neighbor’s roof.
It would probably make a nice tool for campers in areas where you have to store your food in the air or bears show up and maul you. You can get one at ThinkGeek for $29.99(USD).
