hidebo789 5 This item arrived today earlier than expected! The tenderizing ‘hammer’ is a poor casting of aluminum and as a previous reviewer noted it’s worth ¥100!!!Basically it’s junk…alluding to stainless steel is just a hook to catch unsuspecting and fish who trust the description…yes aluminum is mentioned but the casting and finish are TERRIBLE!Look around town or at a cooking store and get something worth ¥1000??
