yeah given the price of three tooth wrenchs it doesn't matter that much. Since all my lockrings only have two notches a three tooth would be kinda worthless for me though.
Also I think you have to keep in mind that with cheaper ones you have have to take a file to the tooth to get it "sharp" enough.
