Nice big knife for props, cosplay or just to scare the living crap out of someone!

Redesign blade for better fit in the handle.
New round holes on the handle with bolts (that you preferably print with the same color as the blade).
Holes are now even 10 mm in diameter (0.393 inches).
Bolts are 9.8 mm in diameter (0.385 inches) with the bolt head at 12 mm (0.472 inches).

Fits nice, use super glue if you need!
