Are three incredibly cheap, really effective weapons that you can pick up and then forget about upgrading for a very long time, allowing you to focus on your armor & jewelry slots. It's really hard to beat the above 3 for cost / effectiveness ratio.
Edit - if you already have the ebon razor, then stick with it and get the other two I listed over time. The green Jade broadsword just has that killer lump of sta / str that is not insubstantial to your dual wield dps + hp bump.
