XP Giver Breaks When Touched by Humanoid? How to Prevent?

I have a script that would give XP whenever a tool touches it. Thing is whenever someone's head or body touches it, it breaks. Is there any way to make it so that only when the tool touches it, it will work, not when a player's head touches it.

XP Giver:

local debounce = false

script.Parent.Touched:connect(function(hit)
    if not debounce then
	    debounce = true
	    local look = hit.Parent:FindFirstChild("BallHandler").Value -- value in basketball
	        local found = game.Players:FindFirstChild(look)
	        local cash = found:FindFirstChild("leaderstats")
	        cash.XP.Value = cash.XP.Value + 5
	        print("Gave +1 SM")
	        wait(1)
	    debounce = false
	end
end)

BallHandler Script:

while wait() do
	plr=game.Players:FindFirstChild(script.Parent.Parent.Parent.Name)
	if plr then
		script.Parent.Value=plr.Name
	end
end
