How to change your Swiss Army knife handles ?
Insert a blade between the knife and the handle, then push the blade a little bit up. After, slide the blade all along the knife to take the handle out. Do the same thing on the opposite side of the knife.
Take the new handles and put it in position on each side of the knife.
Insert the knife into a vice and push slowly to make the handles stick to the knife. Do the same thing on the opposite side of the knife.
Warning : the handles can only be used once; when removed the handles break.
