This is a Hobbit Movie inspired Tauriel Blade.

It can be printed in PLA plastic in 2 simple pieces; the fully assembled dagger measures a length of approximately 19 inches. This model is keyed to fit together with a 1/4" Dowel to help hold the edges true while gluing, making the dagger much more sturdy and it is possible to heft and swing the blade without worrying about it falling apart.
