Why doesn't part follow handle?

So I'm having some weird issue right now. I'm trying to have a player equip a sword. The player holds onto the handle fine but when I add another part to add some detail to the sword, it doesn't stay with the handle when the player equips the sword. The part is strangely elsewhere. What settings do I have to make to this part so that it stays with the handle? It's already a child of handle, so why isn't it staying with handle? Why does the child spawn miles away from the handle instead of with the handle? Even when I made the tool, I set up the child in a way so it's right above the handle, but when the player equips the weapon, the child is not with the handle? Anybody know what's going on? This doesn't make any sense.
