I think it mushes the meat while cutting, if froz you get a much more clean cut as well has sharp blades. Make a big differences in cured raw sausage, you get the nice looking chunks of meat when you cut into the sasuage. If it is not froz or your blades are not sharp, kind of mushes it all togehter. Hamburger, not really sure you could tell the texture differences, you might though. It would be like changing different size plate holes.
