Query: Worked well, for a while.

I found the Norpro professional meat tenderizer a very useful tool for effectively tenderizing less tender cuts of meats and also for pounding seasonings into meat. I liked the long, sharp prongs much better than the usual shallow, dull surfaces of other tenderizers. This tenderizer has a retracting platform that protects the user from being injured on the spikes. However, after a few months' light use, the spring on my tenderizer broke and no longer controls the platform. The spikes are now exposed at all times, resulting in several minor injuries to hands, or whatever body part comes in contact with it. This product was wonderful while it lasted, but now is a hazard.
