How to weld a model to a player

So I have this idea, where any tool in the player’s inventory will be shown on the player’s body. So for example, let’s say a player has a wooden pickaxe, if they don’t have it equipped then it would be welded to the lower part of their torso. (Note: the game is R6). But I’m not advanced with welding and don’t really know where to start off. Does anyone got any ideas on where to start off?

You could turn that pickaxe tool/model into an accessory and use a waist attachment.
You can just edit your script to add the accessory to the humanoid when you unequip.
