the cheese blade is designed to specifically slice soft cheese like mozz or jack etc........ those cheeses really bog down a regular blade.....if you have a sereated blade it's fine, but these slicers dont have that (you can't sharpen the sereated anyway...)..... the 10" is a good buy also at 79 bucks and I'm tempted but then that puts me at way too many slicers, and just for the cheese blade....well......
