Will be down the Cat dealar pronto.
Thanks for the sites, I have read them already, that is why I am after a filter cutter. About these filters, Ford recommend having the pressure relief valve near the top (screw end) of the filter to prevent crap from the bottom of the filter washing back into the engine. I notice Ryco have this valve in the bottom, I bought a Motorcraft filter and it looks exactly the same as a Ryco. Another reason to pull things to bits.
I also have a magnet sitting on top of the filter, so I want to see if this works also, but I don't mind if I don't find any metal.
