I was recently make a knife that throws however I hit an error. It wouldn't thrust when it was activated, but it had no errors.

Please help me out! Code:

    while wait() do
        if mouseDown then
            if tick() - StartedDown > 3 then
                local OldKnife = script.Parent.Handle
                local Knife = script.Parent.Handle:Clone()
                Knife:ClearAllChildren()
                local BV = Instance.new('BodyVelocity')
                Knife.Parent = game.Workspace.Knives
                Knife.CanCollide = false
                Knife.CFrame = OldKnife.CFrame
                OldKnife.Transparency = "1"
                BV.Parent = Knife
                BV.MaxForce = Vector3.new('1e8,1e8,1e8')
                BV.Velocity = player.Character.HumanoidRootPart.CFrame.lookVector * 50
                print('hi')
                wait(1)
                OldKnife.Transparency = "0"
            end
        end
    end
end
