Most listings show stainless-steel cutting wheels; some cutters use smooth, sharp wheels while others use jagged or serrated edges to help separate sticky slices and cut through thicker crusts.
Common safety features include thumb or finger guards and elevated/raised handles that keep hands and knuckles away from the blade during cutting.
Some models combine cutting, separating and serving functions. For example, 4-in-1 designs can serve as a cutter, a spatula for lifting slices, a clamp/holder to grip slices, and include a serrated edge to help separate pieces.
Blade diameters vary across listings; examples include blades around 4.25 inches and larger cutters up to about 8.25 inches, indicating wheel sizes from a few inches up to roughly eight inches.
Listings typically show stainless-steel blades. Handles and other parts are commonly made from plastics such as polypropylene, and soft-touch materials like TPR (thermoplastic rubber) for comfort and grip.
