Product Description
The Global G-39 is a diamond-coated sharpening steel designed to maintain the cutting edge on professional kitchen knives between full sharpenings. Unlike a traditional smooth or grooved steel, the diamond surface removes a small amount of material with each pass, making it effective for realigning and refining edges that have dulled through regular use rather than simply honing them back into position.
In a working kitchen environment, knife edges deteriorate quickly under the demands of daily prep. A good sharpening steel used consistently throughout the shift helps keep blades performing at their best without the need to take knives out of rotation for grinding. The G-39's 305mm diamond steel is a practical length for most professional knives and handles the kind of repetitive, quick-pass use that busy prep work demands. At 370g it has enough weight to feel substantial in use without causing fatigue.
Practical advantages for kitchen teams include:
- Diamond surface removes light burrs and restores a keen working edge efficiently
- Consistent edge maintenance reduces the frequency of full resharpening
- Compatible with the full range of Global knives and most other professional kitchen blades
- Robust enough for daily professional use in a commercial kitchen environment
This steel is well suited to professional kitchens where Global knives are already in use, and to any operation looking for a reliable diamond steel to maintain blade performance across a full set. If your knives are heavily worn or have damaged edges, a whetstone or professional grinding service would be the more appropriate starting point before moving to maintenance with a steel like this.
If you're building out a knife maintenance kit or have questions about which sharpening tools suit your current knife set, the team are happy to help point you in the right direction.

Frequently Asked Questions
- A standard honing steel realigns the edge of a knife without removing significant material, which is useful for straightening a slightly rolled edge. A diamond steel, like the G-39, has an abrasive surface that removes a small amount of metal with each pass, making it better suited to restoring edges that have genuinely dulled rather than simply gone out of alignment. For most commercial kitchens, a diamond steel offers a more practical all-round maintenance tool.
- No — while the G-39 is designed with Global's own blade geometry in mind, the diamond surface is effective on most professional kitchen knives regardless of brand. It works well across a mixed knife set, which is common in many commercial kitchens. If you are working with knives that have particularly hard steel or specialist edge profiles, it is worth checking the manufacturer's guidance on sharpening methods.
- This depends on the volume and nature of prep work, but in a busy commercial kitchen it is common practice to run a knife over the steel every hour or so during heavy use — or whenever a blade starts to drag rather than cut cleanly. A diamond steel like the G-39 is well suited to this kind of regular, brief maintenance use. If knives are requiring frequent attention to stay sharp, it may indicate the blades need a full resharpen first.
