Help On Welding Detail

I Want To Make A Item Go To The Players Hand Based On What The Players Character Is
Example
Player Holding A Bat While Its Character That’s Selected Is A Bat
I Already Understand How it Works In Code But I Don’t Know How To Make A Bat Or Anything Weld To The Players Arm Like A Tool I Already Tried Tools But The Player Would Just Pick It up
Anything Would Help Thanks!
