I am creating a tool and it does not seem to wanna appear in a player’s hand when selected. A Handle does exist in the tool, but I cannot work out on why it then still does not want to appear.

Goal
A physical object as a tool should appear in the hands of a player.
Issue
The goal is invalid as the physical object does not appear.
Concern
A Handle is inside the tool, yet it does not appear.
I have tried to look up the issue, but I cannot seem to find a valid source of a solution for my issue.
Let me know if I have missed something and feel free to link any external links in assistance to solving the issue.
