I do not know the exact size of the Manjushree sword, but I have a Dukti, which I believe differs only in the fuller, handle, and guard. My Dukti, made by Bura, is 27.5" long, 20.25" of which are the blade, and 28.5 ounces. It's about 0.20" thick and almost precisely 1.50" broad. It balances 6" ahead of the guard, very far foward for such a light blade. It and the Manjushree are both double edged.
One thing you'll notice is the blade is
very stiff compared to "modern" reproduction swords, which I've always thought were too much like Wuxia movie floppy noodles. Historical, pre-firearm swords of nearly all cultures were very stiff, probably since no one was dumb enough back then to think that being able to bend a sword in a vise was a mark of quality. One importer of Filipino blades has told the smiths to make their kampilans more flexible for the Western market, which they really hated to do. It totally screws up the cut, you can't chop off heads with a floppy noodle!
Both my HI swords are very stiff, without being brittle or fragile in the least. Definitely more functional than swords I can bend some number of degrees in a vise.
There were also 2 Duktis made by Sher, that sold last year. They were the same length, but around 37 ounces IIRC. They looked much broader, maybe 2".
And I can't think of any reason why they couldn't make you one with a plain handle (Manjushree or Kopis). That'll probably drop the price a little.
