I am using this to cut my cold process soap loafs into bars. I read some of the negative reviews, but I thought it would be ok for my use. Not really. I have trouble cutting straight with a knife, so I thought this would improve my cuts. Wrong! It is so flimsy and wobbly, that now my soap cuts are even worse. And it leaves a 'half circle' of grooves across the soap.After a couple of dozen cuts, it feels like it is falling apart. I'm not sure how long this long this would last for cheese, which is quite a bit harder than my soft soap.I guess you get what you pay for...
