Why Is Tool.Equipped not working inside of starter character scripts?

So I have this code that only runs if the sword is equipped but it doesnt seem to sense if the sword is in hand. Help?

local UIS = game:GetService('UserInputService')
local plr = game.Players.LocalPlayer
local Char = plr.Character
local BlockAnim = script:WaitForChild('BlockAnim')
local Keydown = false
local Hum = Char.Humanoid
local Anim = Hum:LoadAnimation(BlockAnim)
local tool = game.StarterPack.ClassicSword
local ToolEquip = false

tool.Equipped:Connect(function()
    ToolEquip = true
end)

tool.Unequipped:Connect(function()
    ToolEquip = false
end)

UIS.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.Q then
        Keydown = true

    end
    while Keydown == true and ToolEquip == true do
        wait(.1)
        Anim:Play()
    end
end)

UIS.InputEnded:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.Q then
        Keydown = false
    end
    while Keydown == false do
        wait(.1)
        Anim:Stop()
    end
end)

this is was all in a local script and is inside of starter character scripts
