Sharpening a blade

[Highlander]

Of course you don't always need an extremely sharp blade,..it depends what you are trying to sharpen,.... a belt knife needs a sharp edge, a Machete or axe doesn't need to be that sharp.

A blade that hits hard will blunt quicker if it has a very fine sharp edge to it, than it would if the blade was just sharp, when in the Malaysian Jungle, we were always told to sharpen but not to over sharpen
