Is there any way i can detect when a player uses a tool? My way is not working.

In my code, at the if statement on line 21, it SHOULD be detecting when the mouse is clicked. But in my console, it is not printing "Player has thrown a knife." Even when i told it to when the tool is used. Everything EXCEPT this if statement works. But the weird thing is, i am not getting any errors.

ReplicatedStorage.GiveKnife.OnServerEvent:Connect(function(player)
    local humanoid = player.Character:FindFirstChildOfClass("Humanoid")
    if humanoid then
        humanoid:UnequipTools()
        print("Knife deselected.")
    end
    if player.Backpack:FindFirstChild("Knife") then
        player.Backpack.Knife:Destroy()
        print("Knife destroyed")
    end

    myKnife = game.ServerStorage.Knife:Clone()
    myKnife.Parent = player.Backpack
    myKnife.Name = "Knife"
    print("Knife created")

    myKnife.Equipped:Connect(function(mouse)
        mouse.MouseButton1Click:Connect(function(player)
            print(player.."has thrown a knife.")
        end)
    end)
end)
