Push and rotate the bottle with balanced force with all your hands.
Put 2 rubber ring on both sides of the cutting line on the bottle. (The optimal distance between the two rubber rings is less than 10mm)
Rinse alternately with boiling water and cold water (each time for more than 40 seconds) to the cutting line between the 2 rubber rings, until the bottle separates ( NOTE: please use enough hot water, preferably boiling water).
Rubbing the cutting surface with sanding paper.
Tips:
Make sure that both hands rotate the bottle at the same time to get a flat line while cutting and not letting the boiling water overflow between the two rubbers band while pouring(The optimal distance between the two rubber rings is less than 10mm). Otherwise the edge of the bottle may not be so flat.
Please clean up the residual label before cutting the bottle (the glue on the label will shorten the life of the bladehead).
In order to protect the cutting blade, you can use the cutter oil regularly after a long time of use.
