Katana and kodachi for 1/12 figures

Katana and kodachi made for 30MS figures. 
Length is made to look good, I took my own katana as well as a kodachi blade on exhibid Tokyo museum as examples. 
I recommend printing them flat, half-sunken on the bed without brim, with organic supports, and then gluing the two halves together (see photos). I used Tamiya putty to fill gaps afterwards painting them with an airbrush for better looks (blades are Tamiya X-11 and handles XF-1).
Modelled in SolidWorks.
