Change Humanoid to tool?

I've tried to change this script:

script.Parent.Touched:connect(function(part)
    if game.Players:findFirstChild(part.Parent.Name) then
        local plr = game.Players:findFirstChild(part.Parent.Name)
        plr.leaderstats.Sand.Value = plr.leaderstats.Sand.Value + 1
    end
end)
local debounce = true
script.Parent.Touched:connect(function(part)
    if debounce then
        debounce = false
        if game.Players:findFirstChild(part.Parent.Name) then
            local plr = game.Players:findFirstChild(part.Parent.Name)
            plr.leaderstats.Sand.Value = plr.leaderstats.Sand.Value
+1
            script.Parent:destroy()
        end
    end
end)

from touching a humanoid to touching a tool. Is there any way to do it?
