From the moment I saw this handy tool, I loved it. It is the sort of thing you understand immediately. You will think back on numerous times you could have used it. I know I did.
The Thumb Saver is a nail holder, that's all. Shaped just right, with a strong magnet, you can hold that nail right where you want it and hammer away. I don't believe it is for every nail, but there are those places that you need to swing a hammer, that holding the nail with your fingers out of the way is key to prevent bashing them. We have used different methods in the past; needle nose pliars for instance. But this tool works perfectly.
There are two sizes, large and small, and between the two, they'll hold any size nail or brad, staple or screw you are using. A strong magnet holds the nail while you take aim. The grip is good and the construction durable aluminum.
You can check the tool out further and order one from their site: ThumbSaver. And the price looks right, too.
