Show me how it cuts through a fat block of cheddar and then talk to me.

Thats the only thing I wrestle with, and I keep my knives sharp.

Cleaving is mostly about friction. Cutting a block of cheddar is pretty much all cleaving, and a very sharp cutting edge doesn't provide much advantage. My blade vibrates along the blade face, so foods experience the coefficient of kinetic friction, not static friction. This reduces cutting forces, and does so in a way that's totally independent of the sharpness of the edge.

Looks like the inventor posted a comment explicitly about cheddar in the link.

Use wire.

Just do whatever the Dutch do. Which yes, is wire, also those cheese shaver things they have that are so much nicer than they seem like they'll be.

Gotta love a good cheese plane

I tried it once. I buy the BIG CHEESE and these things are too wee. I broke the wire immediately because I'm a ham-fisted goober.

I need the one that's as big as the old paper slicing things they had in school. Put a nice wire on that thing, maybe run some heat through it. Now we're talkin. Also, baller ass way to cut an ice cream cake which is the only thing more impossible to slice than cheese.

The big cheese! I see you are no hobbiest.

(You'd actually want a vaneer saw, but it's hard finding pics of a machine one)

Nah, I'm not gonna be convinced till that thing can slice through an Angel's AT Field.

Serrated knives work better on cheese, unless you need a cleaner cut, then use a wire cheese cutter.

A single bevel serrated knife will leave pretty clean cut though. I use one of these: https://www.williams-sonoma.com/products/wusthof-gourmet-serrated-utility-knife/

Even works pretty well on softer Monterey Jack and pepper jack (which the wire snags on). And I’ve never sharpened it in 20 years.

But paid less than half that at resellers store.

C-200

That is exactly what the CS would name it

This appeared in my YouTube feed yesterday and their pitch video was well done and compelling.

If this is legit as cool as it sounds, it should end up spreading in the market, no? Can it be patented up tight? Or are different approaches possible with slight variations?

Nick@mander.xyz · 2 pts · 334d

Speaking only for the US patent system here, but this can probably be patented in an extremely extensive way. If the company wants to be really protectionist, they could probably get a talented (and extremely expensive) patent prosecutor to keep the consumer kitchen knife market locked down for a while. Any alternatives would probably have to license the patent.

Evotech@lemmy.world · 2 pts · 335d

Idk, depends on the price I guess

Chefs tend to be very traditional though

This looks rad. I don't have 400 bucks to spend on a knife but this seems like more than just a gimmick.

Jarix@lemmy.world · 1 pts · 334d

It's defiantly a knife for nerds who are familiar with Palladium Rifts™ RPG

Think it could cut through a Metal Gear RAY?
