Okay that's fine then, you can just buy a block of cheese and grate it yourself. There are these things called cheese gradters which exist for that very purpose.
You can even, get this, use them to slice the cheese thinly using the slicing part of them.
I've never had issues cleaning them. They aren't super easy to clean but I came up with a method that works well for me.
Put it in a pot, add dishsoap, then pour boiling water in it and let it soak for a bit. Seems a bit weird and extreme but it gets majority of the cheese off of it. There's also a technique involving lemon and salt to clean them.
Oh and if one has a dishwasher that works very well too, but I know many people don't have them (I practically don't, since the one here doesn't work).
Highly recommend getting a hand grater like the ones they use to shred Parmesan cheese in restaurants. Doesn't work well with soft cheese but it's great for things like old cheddar
I don't like the box graters like this one. OXO and Ikea both make nice ones that fit over a container to catch the grate. The OXO has eaten bits of my fingers, though.
There's a trick to using box graters that most people don't know (I certainly didn't until recently)
Lay a towel or some parchment paper in a sheet pan (optional)
Lay the grater on the pan
With your non dominant hand, hold the handle of the grater and the rim of the sheet pan
With your dominant hand, grate, pushing away from you + into the countertop
The mechanics of pushing down/away are much better than holding the thing upright, dangling it over a bowl or whatever. Easy to just push with your palm too (and keep your fingers out of the way).
I usually chop other stuff as well as the cheese. I started doing this when I didn't have a grater, and discovered it wasn't as slow/awkward as I had assumed. The result isn't the same as grating, but it does the job most of the time.
