Can someone help me with a RenderStepped trouble?

So...basically i created a tool that makes your arms visible (even in 1st person) while equipped,but i'm having a trouble with it. The RenderStepped event won't disconnect.

This is my first script (local script)

tool=script.Parent

tool.Equipped:connect(function()
    renderStepped=game:GetService('RunService').RenderStepped:connect(function()
        tool.Parent['Right Arm'].LocalTransparencyModifier=0
        tool.Parent['Left Arm'].LocalTransparencyModifier=0
    end)
end)

tool.Unequipped:connect(function()
    renderStepped:disconnect()
end)

then i tried to make a server script fire a remote event when it's unequipped

--Server script

tool=script.Parent
unequip=tool.Unequip

tool.Unequipped:connect(function()
    unequip:FireClient(game.Players:GetPlayerFromCharacter(tool.Parent))
end)

--Local script

tool=script.Parent
unequipEvent=tool.Unequip

tool.Equipped:connect(function()
    renderStepped=game:GetService('RunService').RenderStepped:connect(function()
        tool.Parent['Right Arm'].LocalTransparencyModifier=0
        tool.Parent['Left Arm'].LocalTransparencyModifier=0
    end)
end)

unequipEvent.OnClientEvent:connect(function()
    renderStepped:disconnect()
end)

none of this worked.
