Most Japanese made iaito tsuka cores I've seen are made by gluing two halves of the core together but a top half and bottom half instead of left and right, as you see on most shinken. so instead of the seem in the core running along the ha and mune edges, they run down the center of the omote and ura sides. Interesting. What brands have you seen that on? I have seen the more traditional style on the couple I have taken apart (i.e. far fewer than you have disassembled) here's a core from a Seido Jisei iaito. I've seen this on Tozando and others as well. so far, I haven't seen a Chinese made iaito tsuka using this same method, those cores have all been assembled like shinken.

How would you go about carving a tsuka core using this method I can’t get my head around it! I’ve been looking at trying my hand at making a new core for a project sword and know it’s good practice to have one side carved deeper to make the two pieces meet off centre to alleviate some stress, but this looks like a much better option for that reason. *edit after looking at that picture it looks like they just carve the basic shape and shim where needed, maybe not as complicated as I'm thinking it is.

my guess is either router bits in these two shapes or chisels in these shapes or a combo. I wouldn't recommend this method for shinken, only iaito.
