Method One using Grenda 

First part is using machine. The result will be sharper, and took a less time. What you need is full bucket of water. Put the knife on bucket and start using grenda to sharpen the knife. It will take no effort for that.

Method two using wungkal or honing stone 

The stone can be divided based on the roughness of the stone. Basically it is divided by three or four. Yeah, try with very roughness first and then more smooth. The result sometime based on the effort of sharpening. I like it that much ha ha, even though the effort is rather meaningless. This method is perfect for knife, but it is rather hard for big knife.

Method three using honing bar or stick 

This is the method for big knife. Just put the stick around the knife, and soon it will be become more sharper. I like this method so much, because it become more easier.

Don’t forget to sharpen your knife every day. Cause if your knife isnt sharp you will get complaint from customer. Yeah, maybe just that the share for today. Hope your knife is stay sharp, and yeah don’t forget to write the report on chicken seller every day.
