The katar is a type of push dagger from the Indian subcontinent.  The weapon is characterised by its H-shaped horizontal hand grip which results in the blade sitting above the user's knuckles.  Unique to the Indian subcontinent, it is the most famous and characteristic of Indian daggers. Ceremonial katars were also used in worship.   

To me, this blade is reminiscent of the Assassin's Creed Hidden Blade.

I used the wikipedia image (https://en.wikipedia.org/wiki/Katar) as shown in the Handy App cover and entered it into Image-to-3D from MakerWorld ([https://makerworld.com/makerlab/imageTo3d](https://makerworld.com/makerlab/imageTo3d)).  I downloaded and imported the mesh into Bambu Studio (the detail of the design is lost in this process but makes for an easier more generic print)

To fit this model (31cm length, 19cm blade) in the X1C build plate I oriented at an angle and used significant supports (without good supports and adhesion this model will fail), 3 walls for strength, gyroid infill and 0.24mm layers (no additional finer detail so less than 0.24mm layer heights are redundant and only increase print time)

As a monochrome print an AMS is not required.   Would advise caution with silk PLA, interlayer adhesion is a little risky with this medium and the supports that are quite tall may fail.

As this is a weapon, please take care in who uses this.   Even though there are no sharp edges, harm could be done with careless play.

I made this for my grandson for use in a history project.   I am not a designer so cannot offer support with changes but feel free to play with your own print settings, resizing and orientation changes.
