Local feral survivors in eight frame medium boxes.
I usually cut mine with a Dado blade on a table saw. But you can also cut them with a chisel or a skil saw and a chisel. You can buy a fancy shaper blade for a shaper and cut them that way and make those fancy looking ones... but mine are usually just a groove 3/4" wide and 3/8" deep and four or five inches long...
