The package arrived this morning and the 'seized' clamps came apart in less than 5 minutes - and made me realise that, like many things to do with spanner-bashing, it's all down to technique.
It's not even skill - a monkey can't operate a zipper .... until it's shown how, then you can't keep the beggar out! I was lucky in growing up around bikers back in the 'sixties, who showed me all sorts of clever stuff ....... and then I became an engineer.

So, I've updated my Skorpion braindump site to include a Tarozzi 'how-to' - http://www.totalaptitude.com/skorp/index.htm
