Step 3: Cutting
If you can do the cutting at the back of the cutters, it’s easier. That can be done a little later.
Using the saw and the block, which clamps to the table, cut out the shape of the cross. Using beeswax to lubricate the blade helps to prevent binding and breaking the blade.
If you don't have a jeweler's saw, a hack saw can do the work if you clamp the coin in a bench vise.
