1, straight hob: the kitchen knife stands upright on the loofah. First, cut it obliquely, then let the inclined plane face upwards, and start to circulate from here. Generally speaking, when cutting the hob block, you will cut it at half of the cutting surface. If you want to cut it into smaller pieces, you should cut it at less than half of the cutting surface.
2. Oblique hob: The angle between the kitchen knife and the towel gourd is between 45 degrees and 60 degrees, so the towel gourd oblique hob only needs to tilt the knife by half on the basis of the straight hob.
