Profession: Engineer/Designer

Inspired by: I am innovative engineer/designer. Once when I was repairing home appliances, I found it rather difficult / uncomfortable to loosen/fasten a bolt joint in the limited space with tradition way using two separated wrenches. I thought that a lot of people would have same experiences as I had. They all deserve a better tool to do this type of tasks. So, I spent a lot of time coming up this design, and hope this tool could benefit millions of workers.
