“Aperture”is the name of the most wanted engine of Jon Steranka. We are talking about a wrench that suit every hex nut or bolt. It sounds crazy? Well after you will see the images below you will understand it all.
The mechanism of the tool allows the artisan to shirk or enlarge in order to fit with the pieces he works with. What is even better is that you can do all with a simple slide.
This engine will surely make life easier for many mechanics. It is great!
