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.

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.
