Fantasy Double Blade

After making my own sword, my mother asked me to design one for her. She wanted a fantasy sword though, so it's not really designed much like the first.
This is a double bladed sword which can break apart into two single bladed swords.
I also used the opportunity to strengthen the sword by including room for wooden dowels. Specifically, Dowels that are 5mm in diameter and 300mm long. and even then, you have to sand down the ends a bit.
Also of note, the dowels are a VERY tight fit. To the point that I ended up having to use the rubber end of a screwdriver to hammer the thing into place. Later on I was able to get a jewelry Hammer and it worked wonders.
But in the end the thing ended up being VERY durable.
I also made it so that at the end of the hilt, I've included space for a door catcher. Specifically, Amerock 0.5 in. H x 1.1 in. W x 1.4 in. D Zinc Steel Roller Catch
