Remember that guy who came up with a new way to make drawers with a dado blade? Well, looks like Rockler picked up his invention. Honestly stoked for the guy.

The sheets are all the same, you'd only have to set your cut depth once and then you could cut all of them. Cutting the side of the drawer with the knife is practically in the same motion as putting it in the proper direction for glue-up. Again, if you're skipping an entire step at the router you could be cutting your labor costs significantly.

Let's do the math on the tape. A 6-pack of painter's tape at Wal-Mart is $7.52 which yields 360 yards of tape or 12,960 inches. Being somewhat generous (about an inch of wasted over-tape per cut) my kitchen drawers would require 108" of tape per drawer. That's 120 drawers per 3-pack of Walmart tape, or just shy of $0.07 per drawer. I feel confident that if you're buying a million miles of tape you can get it cheaper even than Wal-Mart retails it for, so that's on the high end.

So the question is whether or not the labor to add/remove tape + $0.07 in materials is greater than the cost of sending the piece to the router for whatever type of joint it's getting.
