These mallets have attracted a lot of praise. They represent an original and creative use of material which would otherwise have just been binned. Then there is the aesthetic appeal: the bottle top one is simply a very attractive object. I suppose that because this is a highly practical forum, most people would also be interested in how functional they are in the workshop. Incidentally, if they are you might want to patent them because in these days of increasing ecological awareness I can imagine a firm nicking the idea and marketing "green" mallets.
However, it also occurred to me that if the kind of waster who makes a fortune in the ridiculous world of modern "art" were to stumble on the idea, they'd be going for hundreds of thousands. Can you imagine if that p**t Damien Hurst turned out a four foot high one (and I wouldn't put it beyond him) for which some gallery would doubtless pay him more than a million and then had loads of the normal size ones made. They'd be going for hundreds of quid a throw. They'd be seen as making a vital statement about our relationship with the planet.
If I were you, Mr Maddex, I would consider going public with them while talking complete and utter b***locks as often and as loudly as you can and this time next year you'll be supping brown ale in your mansion in Mustique.
