This little model may appear to be quite simple, yet it solves the problem it wishes to overcome. There can't be any household in our technology dominated world that wouldn't have a need for this ! That's what made me put this at the top. Very good innovation and the design is just right !

Good concept with great presentation

Practical and precise design with complete user manual!

A different thinking. I couldn't find anything like this on the internet.

Would like to see it printed and working, could be useful for making underwater tools for various purposes.

When you could eliminate the usage of multiple wrenches, or the difficulty of having to adjust one wrench for each size of the bolt head, using a single tool it is a great achievement. But the stubby design will not be able to be used easily in case the position of the bolt or nut is in a complicated or cluttered area ! Yet in most cases this will do the job for you

A convenient storage kit, especially while touring with multiple gadgets.

Nice and practical idea.

Welding is a crucial task, especially when welding pipes that handle pressure. This tool makes the welders job easier and results in safer piping. Great concept.
