It's good to know that I can make these with a construction tool, and that they can be made with a construction tool. As seen here, and on any page for a basic piece of furniture (non-upgraded).
I don't see the redundancy you mention. Do you mean that you don't like that it says it can be made with a construction tool (in only one location on each basic furniture item page) or are you seeing that it can be made with a construction tool twice on one page?
