I get a monthly newletter from Anything Left-Handed, which is an excellent company that sells left-handed stuff and gives advice on left-handedness etc.
They just sent a newsletter out explaining that they're in trouble financially (they've never made a profit, but do it because they are both left-handed and wanted to supply left-handed stuff to other people)
i've bought loads of things off them in the past and they are excellent.
I found the left-handed carvinf knife to be a brilliant knife (you don't realise that it's not your fault your doorstep slices of bread are thicker at the bottom or completely skew-whiff until you've tried it!)
and i use a left-handed pencil sharpener, and all other sorts of things - my favourites are my left-handed 12" rule and left-handed tape measure.
anyway, just wanted to give them a quick plug, in case it was something you thought about.
their website is:

and there's http://www.anythingleft-handed.co.uk/product_info.html a product info page too
