Throwing Knife with separate blade

I made this knife with a removable blade, more because of the thought of printing the blade a separate color. I plan on making more blades in the future and a different handle but this is just the first prototype. If you like it please leave and review and comment down below what you want to see next!!! When I took off the blade and put it on the handle the first time, it fit pretty snug but I believe you will need to glue it down. I had to glue it down after the second time of removing it, to keep it in place.
