Review on Tandy Leather Deluxe Granite Tooling Slab 6x6x1.1875 inch (152x152x30 mm) 32226-00 by Denise Davis

I used it a few times for setting rivets. He did an excellent job of rolling a smooth, flat surface. I used it on a concrete slab in my garden. I didn't use it for a few months, then I needed it for another project. More rivets. I didn't even hit them that hard and they cracked/split in half. I used the broken half and kept going because I still had to install the rivets and it broke even more. If you use this I suggest putting a perfectly clean surface underneath and maybe a towel between it and the concrete. Either that or on a very sturdy table or countertop.
