    Have you seen the TV ads for the Bavarian edge? They show it sharpening a plastic credit card sharp enough to cleanly cut a tomato. Is it real? Is it a gimmicked tomato? Can't say I've ever tried it, but it would be a clever survival trick if any V-sharpener can really do this. Anyone here ever try?

    Rigged tomato. If you watch the vid (on YouTube) in full screen and pause it, you can see there's a pre-existing cut on the back of the tomato that he lines up with. Notice how after the first couple of failed cuts he carefully rotates the tomato into a specific position for no particular reason, before going to sharpen the CC?

    If you pause it, there's an obvious shadow of a cut on the side facing him, which he then carefully inserts the sharpened card into. You can see it at the very beginning, too, it is already facing him so as to hide the pre-existing cut. Then he first turns the tomato so as to avoid that cut while he fake saws the uncut areas, then turns it back so it's facing him again. He then inserts the card in that cut, and does the rest. So it looks like all he is really having to cut through is the skin on the front part of the tomato.

    You can also see at the end that the bottom of the tomato was already sliced off before he started doing anything to it.

    The earlier scene with the butter knife cutting a "frozen" steak - he shows how dull the top of the knife is, then proceeds to sharpen the bottom of it, which we are not shown in the first place.

    Pull-thorough carbide sharpeners are nothing new. You can get cheap pocket models for a few dollars. They are hell on edges, but if you have totally dull knives, then they do scrape off enough metal to make it sharper than completely dull.

    Well, yours is most assuredly real. Theirs, most assuredly, had a pre-cut on the side towards the presenter and the bottom had been cut off so it would sit flat.

    Whether or not they actually needed to do that is another question. You will notice in their commercial, there weren't little shreds of plastic coming off like on yours. Their goal isn't to sell credit cards as knives, it is to impress the rubes that their miracle tool can make a credit card into a chef's knife.

    You proved that it's a gimmick, because a credit card has the right, thin geometry to cut through the soft part of a tomato if you can make the edge sharp enough to get through the skin the first time. And as you noticed, it didn't keep the edge for long.
