sharpening a knife.

[CrysisMcGee]

Years ago, I head of a way to sharpen your knife with wood. I tried it, and it works....and I have no idea why.

Say you have a large stick with the bark removed that you're carving. It gets dull. What you do is place the edge of the blade on the wood, like you're about to carve, only holding it straight instead of at an angle, and move the blade sideways, left to right, rapidly.

Simply hold it like you're about to cut something, then movie it left to right instead of back and forth.

So it's the opposite of a cutting motion, I guess. and this works. The blade gets sharper.

Anybody have any idea why this works?

It wears down both sides so the edge of the blade gets thinner, and therefore sharper?

...because it works just like a regular knife sharpener?

Only for one side though. But still.

Sorry, I should have clarified better. Simply hold it like you're about to cut something, then movie it left to right instead of back and forth.

As has been said. It works on the same principal as a whetstone, but it takes longer. A stone would probably do just as well, and I can't thing of many situations where you would have wood, and not a rock.

Also Moonlight doesn't dull blades. I know someone who believed it was true, and that pyramids kill germs. WTF?

Exactly.

That's a knife sharpener.
It gives the same reaction as doing that thing.

Well it seems that's it. It just seemed like to me that the blade would wear down when moving it like that on wood. But it doesn't.
