There are various types of whetstones available and normally a medium grit stone is sufficient to start with. However, if the blade is blunt or damaged, it may be necessary to start with rough grit.

Regardless of the size or type of stone you are using, the procedures for sharpening are as follows:
1. The stone should be soaked for the required amount of time before use, approximately 10-15 minutes.
2. Hold the knife so that the blade meets the stone at a 10-15 degree angle, then push back and forth across the stone in smooth steady strokes maintaining the same angle.
3. The key to maintaining the same angle is hearing the same sound with each back-and-forth stroke against the stone.
4. Repeat the step above on both sides of the blade going from one side to the other until your knife is sharp and there are no burrs on either side.
During sharpening a certain amount of wet powder will appear, but do not wash or wipe this residue and continue sharpening. Although this powder appears unsightly, it is this residue which sharpens the knives.

After sharpening, your knives should be washed in hot water and then towel dried.

NOTE: Achieving the correct angle is sometimes difficult, particularly for beginners. Most GLOBAL retailers will carry a product called MinoSharp Sharpening guard rails. These guard rails will help you achieve the correct angle when using a whetstone.

For some people, learning the skill of intermediate sharpening with a ceramic or diamond rod is difficult. It is essential that you maintain your knives on a regular basis and proper sharpening will help them last longer. The ceramic and diamond rods are used in the same way that traditional steels are used to sharpen knives. The diamond rod is harder than the ceramic rod and will bring back a knife edge quicker. The diamond rod also will not break if it is hit or dropped unlike the ceramic rod. However, the ceramic rod will give a finer edge if used regularly and replacements may be purchased if necessary.

NOTE:
• DON’T use traditional steels made from other materials as they are likely to damage your GLOBAL knives.
• The ceramic steel through use can discolour – this is residue that has built up in the pores of the ceramic. Use warm soapy water and if necessary a scourer to help keep your ceramic steel clean.

For some people, learning the skill of intermediate sharpening with a ceramic or diamond rod is difficult. It is essential that you maintain your knives on a regular basis and it will be easier to maintain them for the long term. Most GLOBAL retailers will carry one of these user-friendly devices called MinoSharp, MinoSharp Plus, or GLOBAL. These are hand held ceramic water sharpeners and no experience or skill is required to use them. By simply filling the reservoir with water and running your knife backwards and forwards a few times, the ceramic wheels ensure the blade is sharpened at the correct angle.
