Good expressions for how sharp a knife is

[Thomason]

Another one from Mr. Fisk......Will slice the Christmas ham so thin the relatives will go somewhere else next year.
(something like that, hope I got it right)

MInd-bending answer: Sharp enough that when you cut a tomato, the slice has only one side.

So sharp "it will shave the hairs off a flies leg"

Over in the Himalayan Imports forum we talk about things being 'full body shiver' sharp....given one's state of being upon feeling the edge....

This came up in a few other threads and somewhere I coined my favorite phrase to date:

murderously sharp

 

[efros10]

caterpillar eyelash sharp!!!

 

[Sticky]

[cds1]

Ouch! (To me, that says it all.)

 

[CRH]

"How sharper than a serpent's tooth it is
To have a thankless child!"

Shakespeare, King Lear (Act 1, Scene 4)

"He'd be sharper than a serpent's tooth, if he wasn't as dull as ditch water."

[Megalobyte]

Sharper than the tounge on a 2 dollar whore...

I like "stupid sharp". Kinda funny because you could say it's so sharp it's stupid because it wouldn't be practical for anything. You could also have "Oh my god I cut a 3 inch gash in my leg and I didn't even feel it, sharp!"

"So sharp it'll make a razor blush".
Bill Bagwell wrote that phrase in an article one time, always liked it.
