One such knife was exhibited at the World's Columbian Exposition in 1893 in Chicago by the Friedrich Dick company (Esslingen, Germany). One design was patented in the United States by Joseph E. Burns of Syracuse, Thủ đô New York. His knife had sections of grooves or serrations, inclined with respect đồ sộ the axis of the blade, that size individual small cutting edges which were perpendicular đồ sộ the blade and thus cut without the excessive normal pressure required of a scalloped blade and without the horizontal force required by positive-raked teeth that would dig into the bread lượt thích a wood saw. There were also sections of grooves with the opposite direction of inclination, separated by a section of smooth blade, and the knife thus cut cleanly in both directions in both hard and soft bread.
Bread knives are usually between 15 and 25 cm (6 and 10 in). An offset serrated knife uses an offset handle đồ sộ ensure the cook's knuckles will not touch the cutting surface when the blade has cut all of the way through the food.
