It uses a sliding dovetail joint to connect the two parts. The joint came out better than I expected but I don’t think I will use it for any future crepe spreaders. A wedged through mortise and tenon seems like it would work better.

It’s pictured without a finish. I’m going to give it a very light once-over with some sort of oil (probably olive oil) just to make the surface a little easier to clean after use. Otherwise, it’s not worth really giving it any sort of extravagant finish because it will see a fair amount of wear anyway.
