At last I have found a forum to have a general natter about woodworking tools etc.
Here in the UK we have excellent mail order from a co called Screwfix.
I realised I was hooked when I found myself reading their catalog for pleasure. you might find it hard to imagine a grown man salivating over the merits of 'turbogld' screws. But actually these screws have transformed my practice. Previously drilled three times for conventional screws. Now just press the razor point to the wood and away we go. These screws are self countersinking.
Oh dear, I have got quite carried away!
