Very cool and very clever, but if the goal is speed and simplicity what makes it better than cutting a v-groove with a router and folding that together? Is it that much stronger? Seems like something worth patenting, but unless the shape isn't as relatively arbitrary as it seems, surely there is some variation on it that's better in some way, and could you patent that? Seems like it might be jumping the gun to announce it before iterating the design and perhaps applying some computer analysis.

Well, it does offer more gluing surface than a straight V cut, and in various directions. Both of those things should add to the strength of the joint. That said, it does seem a repeating 'saw tooth' pattern might do even better.
Odd, on youtube, it did have a 'patent pending' notation when he showed the pattern/blade. I didn't see it when I watched it again here.

Great idea.

For added strength could insert some dowel rods.

This is sex for woodworkers, except you don't feel like a nap afterward.

The guy could give classes in how to make a video. Very well presented, excellent pacing and use of fast motion for the slower parts.

Frickin *quality.

I love ingenious ideas like this that come to life and are as awesome or even better than imagined.

So cool.

Maybe the patent pending didn't show because annotations are turned off on VS by default.

This is very smart, but also disappointed that he wants to patent it.

Yeah, I was like, "Oh, that's so cool! I can't wait to... Oh, crap. I'll never see this invention in my lifetime."

If he has a custom builder for the blade, why doesn't he just do it himself? Go on kickstarter or something to get enough orders to do a large bulk run with enough room to make some money, do the run, send them out to your backers, and then hopefully you'll have enough to start your business and quit your day job.

Great video and now all I can smell is freshly cut wood.

Well to answer why he is not kickstarting it, he stands to make a lot more money in the short term by patenting it and then selling the patent to a tool manufacturer. Just like big oil and other companies, they buy up patents like this to prevent them from being made. This would cut down on the blades and tools you currently use to make corners and they want to sell more stuff overall, not less stuff that does more.

I like the fact he actually observes proper saw safety. (Running without a fence guard is required in some instances)

Seen some how-to videos here on the Sift that make me cringe.
