The Evangelion progressive knife is a high frequency blade that cuts through matter on a molecular level. It’s not yet quite possible to own a real one (technology isn’t in that level of cool just yet) so for now you’ll have to be satisfied with the current merchandise. I’ve listed down the licensed ones below.
Progressive knife ruler. A ruler inspired by the form of the PKN-01C, it’s shape is still quite far from a replica. But it would probably be impossible to hand-carry in an airplane.
Evangelion cake series. I never would’ve expected the franchise to actually sell food products, much less cakes, but its main feature is actually the dinnerware that comes with it. Made of stainless steel, the dinnerware is fashioned after Evangelion bladed weapons such as the Lance of Longinus and Mark 06’s Spear with display bases featuring Rei and Kaworu, respectively. There’s one with EVA 02’s progressive knife that “cuts” into an Angel-core shaped chiffon cake of some sort, featuring an Asuka base.
The cakes aren’t sold outside Japan, but the dinnerware and their bases are occasionally available on eBay for ridiculous prices. Here’s one of the Longinus Spear with a Rei Base.
Progressive knife… chocolate! Released years ago, I doubt if any of these are still available, but if you managed to buy one, it would be wise to refrain from eating it… knives after all, aren’t the most edible of things
Movic Evangelion Progressive Knife Replica. Released in 2008 as part of the merchandise for the 1.0’s theatrical release, the vinyl replica of EVA 01’s progressive knife features a locking mechanism that allows it to fold exactly the way it does when it’s stored inside the EVA 01’s shoulder pylon. It sold Y5000 (around $50) when it first hit the shelves, but the one I chanced upon and bought new-in-box on eBay this year from a Japanese seller went for thrice the retail price, possibly due to a very limited release.
Museum pieces. Commissioned by the Bizen Sword Museum, these progressive knives, along with a lot of Evangelion-inspired pieces, are currently on display at the Osaka Museum of History. More than being pop-culture artefacts, these priceless relics are real weapons forged from premium tamahagahane steel by traditional Japanese swordsmiths and craftsmen. They’re not onsale, but it will be someday. One day…
Don’t let this list of rare, expensive or plain unavailable progressive knife merchandise make you despair! One way you get one of your own is to make a papercut model of it, which not only look terrific, but is fun to make and FREE! Here’s the link.
Better yet, you can wait until Ginton Forge releases its upcoming resin progressive knife replica with effects built in!
