Being in the US, I had to search for 'Rawlplastic'.
I see that though now being made of plastic, they are still called 'Rawl' plugs.
Very interesting post, thank you.

I had a friend who died of mesothelioma and i found it fascinating that although the asbestos was inhaled the meso was OUTSIDE her lungs in the pleural space. Now the last time I looked, the lungs were airtight, so how did an asbestos fiber, much bigger than an air molecule get to be there?

Mesothelioma is defined as cancer of the tissues lining our organs; most commonly the pleural space around the lungs. Asbestos fibers can travel through the aveoli into surrounding tissues; in fact this is the reason it causes both mesothelioma and asbestosis, which is the mechanical scarring of lung tissues by inhaled asbestos fibers.

Do you think that sharpener automatically advances or does someone have to move the blade and lock it in place...

I am looking for something to give me a sense of scale and all I can see are the cabinet doors. I am guessing the blade to be about 4 foot diameter. I wonder how far wrong I might be.

This is Mesta...it could be 40 ft :-)

I think it is automatic; can't think of another reason for all the linkages behind it.

In which case, that would be one hell of a cabinet
