If you could invent a gadget what will it be and why?

Several months ago, I had made a wooden chair. In fact, I am maladroit at the woodcraft. Therefore, the process of making that was so painful for me. Especially, I could not get a stuck nail out, since it was stuck firmly. Just at that time, I thought how convenient it is if there were some devices to be easily able to get a stuck nail out. Therefore, if I could invent a gadget, I will make something like a device getting a nail out.

Hello there! Thanks for writing despite the difficulty. I think it is  a good idea. You based it on what you needed. Maybe, in the future, if you have time, you can also try to make it.^^ Why not, right? Anyway, see you tomorrow! ~T. Jessie~ Several months ago, I had made a wooden chair. >> Correct!
