Sharpening tip

Anyone remember the Patulin/Apple juice scare? As Anne Diamond FAILED to point out, you'd need to drink something like 20 GALLONS of apple juice a day for 10 weeks IIRC to die of patulin poisoning, by which time you would have died of Vitamin C poisoning, heart attack from the quantity of water entering the blood stream and diluting your electrolytes and half a dozen other reasons.
Anything you read in the press, take with an EC salt mountain...

You can't die from vitamin C poisoning. Excess vitamin C is eliminated from the body, which is seen as diarhoea. Annoying, maybe dehydrating, but if the cause is a vitamin C rich drink, then maybe this is not such a problem.

Vitamin D, on the other hand, in very high doses can be a problem. I've heard of pregnangt women taking vitamin D supplements, who read that "eating lots of liver is good" having sometimes suffered from overdoses.

Doesnt lettuce contain a poison that in small quantities is good for us?

I seem to remember somebody (Boaty?) suggesting eating lettuce for supper in order to sleep better in hot weather.

Lettuce sap contains an opiate. Lactuca virosa and lactuca canadensis contain more than commercial cultivars, but still, the milky white sap (origin of the name lactuca) contains a very mild sedative that might be just enough to push you into the land of nod.

No doubt, if you drain eight pints of sap from lettuce plants, and drink all of it in twenty minutes, you will feel a bit dizzy, maybe nausea and vomiting will follow. Ann Diamond really should investigate the stuff freely available at the greengrocer's shop!

Ah, sorry, long time since I was a scientist ( I know it turns your skin yellow in excess) but it just REALLY got on my nerves that she totally ignored the work I was doing just to hype up the stories for the press...

Lettuce is sufferitic(sp) i.e. contains chemicals that make you want to sleep,no idea on the amount you would need to eat, this fact has been known as detailed in Beatrix Potter's Tale of something Rabbits, where all the young rabbits ate the lettuce from the garden only to fall asleep and be bagged up for a pie. Now don't even ask how i remember these things when 9 times out of ten I can't remember what I did a few days ago.

Soporific, I think you mean.

Must be the "Tale of Peter Rabbit". I don't remember the little rabbits falling asleep in that story (maybe in another story), although Mrs (Jessica?) Rabbit warns her offspring to stay away from Mr MacGregor's garden, saying "your father had a nasty accident up there, and ended up in a pie".

There is mention of Peter feeling sick, so he eats parsley to cure himself.

The particles of PFTE in suspension fill in the irregularities in the surfaces that rub against one another, to reduce friction.
The whole point of a sharpening stone is to have a controlled degree of wear, in order to remove the metal.
If you don't want to remove metal, you don't grind. You use a smooth steel the straighten the edge without removing metal.

This is all very well but if you keep on applying the PTFE you cannot get a controlled sharpen as you will have to push the stone harder to enable the same cut. In order to get consistent grinds you should keep your stone clean and flat, thereby keeping the same grit. Happy sharpening
