when using a serrated knife i have read the motion to use is a sawing motion( back and forth) or a long pull But seen where people also use a serrated knife like a chef knife when cutting items to. Example for what some call a low cut ...tip on board, back handle of knife drawn back then a forward down to slice through food.......this i usually do with a chef knife bec. of the belly. But now see a serrated knife use the same way....tip on board, back of handle of knife drawn back and then a forward down to slice through food.......nothing like a saw motion back and forth. Could some one explain why a serrated knife is used this way .....beside the way i been reading back and forth saw. Or share there thoughts or ideas.
