This turnbutton tool has been around fro quite a number of years. It's a heavier version of our design. Would be suitable for hundreds of punches. Very robust.  The turnbutton tool is designed to be struck with a hammer to punch a hole in many fabric materials to make fitting a turnbutton common sense eyelet and washer a simple task

A little tip I use : Most people use a block of wood under the canvas when using similar tools. That can work fine, but also grab a magazine, something similar to a TV times and place it between the block of wood and the canvas then give the hammer a go. I think you will be impressed. 

This listing is for 1 tool only. 

This turnbutton tool is to be used only with turnbuttons. Will not fit lift the dots
