Thank you for viewing. This is an item from a noodle factory. I am selling a cutting blade that I used previously. The #22 blade is for medium-thick Chinese noodles. To add waves, please purchase a plate and a silicone rubber. It is compatible with Ebis Menki and Tokizawa Menki noodle machines, but I do not know about others. It is old, but the teeth are all intact. I checked it by running it in a noodle machine, and it rotates smoothly without any unusual noises. When handing it over, I will clean the grooves by running noodles through it before shipping, so it will take a little time.
