The bone cutters I purchased from BRS are crap. I cleaned and wiped the cutters dry after each use and the screw that holds them together seems to be rusting. It's so hard to open and close now. They are stainless steel but I think I should have gotten surgical steel instead. I see good reviews for the Boston Aquafarms cutters but does anybody have any recommendations for others? I'd prefer to buy local rather than buying online.
