I have to give the inventor of the Simple Harmon Farms decapper the due credit here, as they must have put a lot of effort into this, and surely addressed many issues during development. If you don't like bare aluminium, you can have it anodized with either of a variety of coating options, very cheaply. Or machine the parts in stainless steel, but that will cost you more than what this is being sold for. Im not aware of what the Honey Paw Slit Decapper is made of, but they found the need to steam heat their apparatus for it to work correctly on all cappings, but the honey paw does not rotate though. I am keen to get more feedback from those that have actually used it and, if good, purchase one before the price doubles.
