Also press on the top of the knife instead of only using the handle. And cut it on an angle so it’s not trying to press down on the whole length at once. And don’t try to pull the blade towards the handle (which is usually the ideal way to cut) if you’re cutting that much cheese because it grips the entire length of the blade and that might have more force than the handle can handle (heh), like in this case.
Lubricating the blade could help, maybe use a nice chili oil to give the edge a bit of a kick.
