It's been years since I've laminated a table with Formica. I just used a very sharp combo blade on a table saw. I think the Formica is a phenolic so you may want to be careful of the dust and fumes. the other way you can cut it is the score it then snap it. Cut it large, run the laminate over the edge, trim with a router bit with a ball bearing guide after gluing it to the table.
I used contact cement to glue the Formica to the table top.
The extra stuff, you can laminate several layers together to make thicker stock for knife handles.
