Meat ax)
, a circular blade, and very thick, as shown, fruit knife, whole is smaller, blade is long and narrow, quality of a material is lighter.
The blade shape is determined by their purposes, for the meat knife, to cut the meat because it is over, at the same time, also stamping meat bones, so I need quality large knife, when kitchen knife to cut the meat or at a certain speed 'stamp' meat bones, the quality of the chopper will generate large force of the food, so as to achieve the purpose of cutting food, for the fruit knife, cut fruit, relatively fragile, so when cutting, don't need a lot of force, so the quality of a material is lighter fruit knife, inertia small, easy to operate.
Three bones if 'stamping with a knife, a knife, when bone knife the front end of the contact, hand feel knife downward, upward, conversely, there's a position that stamping on the knife to the object, the feel is very relaxed, this is because the circuition every object has a' hit the center, when the force of the action line through 'strike center', 'hit' force of rotary axis is zero, the butcher often used to stomp meat meat ax blade is round, this is for the 'stamp' meat bones, no matter which one part of the force in contact with the meat bones, can guarantee the meat bones of cutter forces basically through the axis of rotation of the handle;
Hit the center ', so you can reduce the stamping meat knife the opponent.
