Fast, Effective Edge Maintenance.
A sharp knife is safer, more enjoyable to use and delivers cleaner, more precise cuts. The Global G-38 Diamond Sharpening Steel features a diamond-coated 26cm rod that rapidly restores the cutting edge of kitchen knives, making it an excellent choice for busy home cooks and professional chefs who need fast, reliable results.
Harder than ceramic sharpening rods, the diamond-coated surface removes a small amount of metal with each pass to quickly refresh tired edges. It is suitable for maintaining Global knives as well as other premium quality kitchen knives and offers a practical solution between complete sharpening sessions on a whetstone.
Handcrafted in Japan, the G-38 is balanced for comfortable handling and consistent sharpening. While the diamond coating is exceptionally durable, it will gradually wear with years of regular use, providing many years of dependable performance in the home and excellent longevity in commercial kitchens. For restoring a completely dull blade, Global recommends using a quality whetstone before maintaining the edge with the G-38.

Use & Care:
- Use regularly to maintain your knife’s edge between complete sharpening sessions.
- Hold the rod vertically on a stable surface and draw the blade down the rod at approximately a 15-degree angle, alternating sides with each stroke.
- Apply light, even pressure and allow the diamond surface to do the work.
- Hand wash if required and dry thoroughly before storing.
- Store where the diamond-coated rod is protected from knocks and unnecessary abrasion.
- Avoid excessive pressure, as this may remove more metal than necessary.
- The diamond coating will gradually wear over many years of use but is designed to provide long-lasting performance.
- For completely dull knives, use a quality whetstone before maintaining the edge with the diamond rod.
