NEWS – If you’re like me and have a thing for carabiners, you need to check out the U4 from RovyVon. It’s made from lightweight but strong Titanium, so it has that going for it, but it also features a built-in folding knife that uses readily available replaceable scalpel#11 blades. Use it to open packages, sharpen pencils, cut string/rope, you name it. And when the blade gets dull, just snap in a new one. The U4 Titanium Carabiner from RovyVon is $32.95 from Amazon. If you get one, and let me know what you think of this little multi-tool.
