Joining two pieces of wood with nails leaves the head sticking out, especially if you join them at a 45 degree angle.

Introducing the dual sided nail. Looking like two nails joined at the top, you take the two-spiked nail, and insert one end into a special cylinder that allows you to pound it into a piece of wood without blunting a spike. Then you pound it in. Then you place the second piece of wood on top and smack it really hard to join them together in an oak/maple matrimony.

Hammer nails half in. Angled cut with a wire cutter. Place second piece of wood on top. Hammer. Done.

There are some rather nice double ended screws that I used to mount the wooden balls on to my newell posts on my staircase.

You would have to be deadly accurate to fasten a mitre joint using your idea. Once you hammer the second piece of timber onto the spikes, that's it! How would you line them up with any precision?

I'd like to buy a dowel.

Much relieved, I thought this was going to be about fingernails...

I'm sorry, I don't know if it would be considered baked, but I just do what neeladan does.
