CAPE GIRARDEAU, MO (KFVS) - The Edge of Glory Knife Sharpener makes some pretty big claims for a tiny little gadget.

It promises to be the "world's best knife sharpener." Lydia Alford and I are ready to slice and dice our way through this test.

We see it has the suction holding power to stay in place, but can it sharpen our very dull knife?

The knife we have can't even slice through a ripe tomato. We swipe it through the Edge of Glory sharpener where it sounds like the carbide blades are sharpening, but can it cut?

Lydia gives it a try and says it seems to go more smoothly than before we sharpened it, but we still had to pierce the tomato first.  The Edge of Glory didn't sharpen this knife like it shows in the commercial. We sharpen it several times. Still, it takes some effort to slice with it, and it seems our cheddar is sharper than our knife.

"I was a little disappointed," said Lydia.

Next, for fun we see if this can at least sharpen a credit card, like the commercial shows! Why you'd want to slice a tomato with a credit card, we don't know, but Lydia and I proceed, first checking to see what happens before sharpening it.  It does not cut a tomato on its own.

We swipe the credit card through the sharpener and then the tomato. It easily glides through now!

"So, when in doubt, you can cut your tomato with a credit card!"

Still, we're not laughing at this point: even if this did sharpen all knives, which it does not, eventually the carbide blades will dull, too, and you can't replace them with this product.

"You can spend more money on a higher-quality sharpener that even has replaceable parts than this," said Lydia.

We're positive this is not the "best sharpener in the world," as promised.

"I'm thinking a 'D'," said Lydia.

The $10 Edge of Glory doesn't make the cut. It's off the cutting block with a 'D' on this Does it Work test.
