Regular peelers slide helplessly over tomato skin. The old workaround (blanching then ice bath) adds time and dishes. PROGRADE's micro-serrations bite into delicate skins just enough to catch and cut, without pressure that crushes soft flesh. Same serration principle used in surgical scalpels for soft tissue. Beyond tomatoes: peaches, kiwi, plums, nectarines, ripe pears. If you make fresh tomato sauce even occasionally, the time saved vs. blanching makes this tool obvious.
