When inserting the rivets we recommend using a very solid surface like a cement floor so there is no movement. You will just need a hammer to set the rivets, but you will need something to make a hole in your leather, we recommend a revolving hole punch. 
Webbing Version:
Metal sliders 2 x 1″. The sliders you need will slightly depend on the webbing you use, if you are using our plain webbing or Long Road webbing these loops work the best.
1.6m of webbing 3cm wide. We recommend our Long Road, or Plain Webbing.
