The Octane butterfly knife is absolutely one of the most attractive heirlooms in Apex Legends.
I received a lot of e-mail and messages to motivate me to make an Octane balisong metal replica.
And finally, I decide to do it this May.
It takes me a week to search the data about it and draw a 3D model of it.
About 1 month to make the metal mold and paint it.
Finally, I finished the 1st prototype in early June.
