About this 3D model

My son wanted to cosplay as a player from Dead by daylight video game. I used imagines from the DLC to create this knife he uses. I used clear petg (all I had) for the glass blade. The black PLA. I used no supports but looks like I should have. At the bottom on the knife it curves a bit and had some over hang. But it gets tapped up in yellow tape (Police tape) so not to bad noticing.
