How to disable unequipting a flashlight

Mark it as solved then.

Also what’s stopping you from getting a Motor6D, attaching it to the Right Arm (just like tools) and not have to use tools at all? You can animate other parts that aren’t usually found in a Character model with Motor6Ds. This will prevent the use of the flashlight as a tool and what not. You can follow this guide for reference.

Just disregard the whole tool setup.
