The screw most likely isn't stripped, it probably just went past the threads of the hilt.
It's certainly stripped, that screw aint moving. The allen wrench slips inside it and can't grip onto the hex slot anymore. Unless they have an EZ-Out for allen-wrench screws, I think I'm just stuck with this blade color and length

I got the Adegan Silver color, and it had an orange color disk and 36" UEHG blade inserted at the time. Looks like that's how this one's staying.
