That blade is not infinitely long unless you measure the same part over and over again.

Fr, what happened to 2πr?
A sword by definition has a "pointed blade" accordingly any object with an infinitely long blade cannot be a sword. Rather, it's a blade ray.
it does have a point. look at the blade from the side.
pointy bit goes into the pizza.
Instructions unclear, pizza cutter stuck in pants and now I am circumferenced
Circumcized?
Circumnavigated
If she's doing it right
I know what I said
Swords without a sharpened point had existed. You could only use them for cutting, not thrusting.
I was going to define this as an axe
Im not sure what defines a strike but im pretty sure you wouldnt thrust a pizza cutter. If we're being technical, it doesnt meet the whole definition.
I have used it this way to cut through some really crusty pizza.
strikes are possible.
No that's a pretty finite length, even if you have to measure the atoms to do it.
Wait. Of the blade or the whole thing?
It’s also not length but circumference.
You don't need to leave the kitchen, just need a pi
Diogenes has entered the chat
I have used a pizza cutter to cut more than one pizza. I have also wielded a sword, (Ren Fair and fought a dual), and cut pizza with it. I have also field dressed a couple of deer and cut a few pizzas, (along with apples and sandwiches) with a Victorinox Classic keychain pocket knife over the years.
Of the 3 pieces of cutlery, I find the Victorinox Classic to be the most useful.
Yo. New Diogenes just dropped.
A kid in the show Happy Face tries to bring one to school as a weapon. The parents talk about it after he leaves and think it's funny he considered that to be a weapon.
the pizza cutters i have experienced in my pizza career often fail to cut through the pizza
It specifically says for thrusting or striking. That's where the pizza cutter fails to pass as a sword. 😔
You put the sharp edge on a surface and push forward to cut pizza. That IS thrusting.

Thrusting or striking, you can definitely strike with a pizza sword so it match at least one definition.

This image makes me angrier than it should. Those 4 "right angle" designations are all lies. You cannot have a curved line attached to anything and call it a "right angle". It's not. Like, factually. I don't care if it's 2 feet long, or 200,000 miles, it will never be exactly 90°, which invalidates the entire thing.
OK. Walk in a straight line for a couple of metres and stop. Rotate left or right by exactly 90°. Now take a curved path in any direction.
Did you or did you not turn 90°?
That doesn't make the resultant diagram 90° at those vertices. That's just empiricist stupidity.
OK, then what angle is it?
If it’s not a right angle, then what is it? Wouldn’t you just measure the angle between the tangent of the curve and the line? Working with the tangents is how you find the angle between two curves as far as I know. You say it will never be exactly 90 degrees, but it would be 90 degrees at exactly that point. That’s not a weird thing to say from a math perspective.
I think a bigger issue with this figure is that they’re using some internal and external angles for their count of 90 degree angles. (And that this is just a ridiculous twist on a square, lol.)
This is not a parallelogram and is therefore not a square
ah yes, ignoring that it should actuality be a polygon, implying a closed shape with straight sides much like this ignores the "weapon" and "used for thrusting or striking" parts of the definition.
not hard to make strange things fit a definition when you just ignore parts of it.
Let me introduce you to the Non-Euclidean surfaces to bend your concept of straight lines
something tells me neither of these are genuine attempts at properly using the definitions but rather clever subversions with deliberately obtuse interpretations in pursuit of... checks notes... humor.

If Leonardo can use katanas to slice pizza, then I can use this (while pretending to be a turtle)

Well it's not infinitely long. It's pi D's long. With D being.. well, let's just say my "peanits"
I heard a comedian call these "infinity knives" a few years back, and now it's all I can call them.
