I'm calling this my Square Interlock corner joint, An alternative to half blind dovetails,

Sample was cut from a pine panel scrap. Thus the variation in end grain showing.

I've posted more photos, including of it with both sides before gluing and some renderings from Aspire on

That is one cool and unique looking joint. Undoubtedly a very strong joint. Thanks for sharing the idea and the end result.

I had to try one more variation. This one I call my Half Blind UpDn Diamond corner joint.

Apart. Made this from oak and walnut for some contrast.

Together. No glue yet. Fit required a 0.003 allowance on the oak side vector for a slip fit that doesn't require beating it in with a mallet.

Time consuming to cut using a 1/8" end mill. Both boards are close to .72" thick.

Glued Up. Sanded to 400 grit. One coat of Tung Oil only on the outer faces.
