Sharpening Knives in the Gastronomy Industry: Why Sharp Blades Save Kitchen Workflow
A blunt knife is the hidden bottleneck of every professional kitchen: it slows down the mise en place, ruins the cut appearance, and is the most common cause of cutting injuries. This guide shows why sharp blades noticeably speed up kitchen workflow, which sharpening method is right when, and how a routine can keep your knives ready for use permanently.
Why Sharp Knives Determine Kitchen Workflow
In a commercial kitchen, cutting takes place for hours every day. Whether the blade glides cleanly through or must be pressed and sawed determines speed, quality and safety:
- Work safety: Blunt knives require more pressure — if the blade slips, typical deep cuts occur. A sharp knife follows the guide and is the safer tool.
- Speed in mise en place: Those who cut onions, vegetables and meat with a clean pull instead of squeezing save seconds with each action — over a kitchen day this adds up to noticeable working time.
- Cut appearance & product quality: Smooth cut surfaces on meat, fish and vegetables not only look better — they release less cell juice, keeping produce fresher longer and cooking it more evenly.
- Ergonomics: Less force means less fatigue in wrists and forearms — especially during long shifts at the cutting board.
- Fewer downtime issues: A well-maintained blade requires less frequent and costly re-sharpening and lasts for years.
Honing or Sharpening? The Methods Compared
Important to distinguish: Honing (with the honing steel) only realigns the fine edge of the blade — it removes hardly any material. Sharpening (stone, machine or pull-through sharpener) grinds a new edge when honing no longer helps.
| Method | Purpose | Effort | Suitable for |
|---|---|---|---|
| Honing steel | Daily edge realignment | Seconds, before each shift | All smooth blades |
| Electric knife sharpener | Regular re-sharpening with consistent angle | 1–2 minutes per knife, no skill needed | Kitchens without sharpening experience, consistent results |
| Honing/sharpening stone | Basic sharpening and fine finishing | 10–20 minutes per knife, practice required | High-quality chef’s knives, ambitious cooks |
| Sharpening service | Heavily worn or damaged blades | Drop-off/shipping, cost per knife | Complete overhaul, serrated edge repair |
For most commercial kitchens, the ideal combination is: hone daily, regularly re-sharpen with the electric sharpener. Devices like the Bartscher MS310 keep the sharpening angle automatically constant — thus even without sharpening experience a reproducibly sharp result is achieved, even on serrated edges.
The Sharpening Routine for Every Kitchen Day
| Frequency | Action |
|---|---|
| Before each shift | Realign blade with the honing steel in 3–5 strokes per side |
| Weekly (with intensive use) | Test sharpness (paper or tomato test) and re-sharpen if necessary with the electric sharpener |
| Monthly | Thoroughly sharpen all knives at the station, check blades for chips |
| Continuously | Only cut on plastic or wooden boards — stainless steel surfaces, glass, and porcelain dull any blade |
| After sharpening | Clean knives and store hygienically, e.g. in the UV knife sterilizer |
Sharp Alone Is Not Enough: Why Sterilisation Matters
A knife moves back and forth in daily kitchen use between raw meat, fish and vegetables — making it one of the most frequent carriers of germs and cross-contamination. Especially after sharpening cleaning is mandatory: fine metal residue is generated during grinding, and the freshly sharpened blade goes back into food contact immediately.
- Work HACCP-compliantly: Hygienic storage of knives is part of every self-monitoring concept — a UV sterilizer visibly documents that blades are stored germ-free.
- Stop cross-contamination: UV-C light reliably reduces germs on the entire blade — including areas where cloths can’t reach, e.g. blade spine and handle base.
- The correct process: Sharpen → clean and dry thoroughly → hang in the UV knife sterilizer. Every shift starts with sharp and hygienically impeccable knives.
- Storage included: The sterilizer replaces loose drawers — blades hang individually, do not touch each other, thus staying sharp longer.

Frequently Asked Questions
How often do I need to sharpen knives in gastronomy?
Honing belongs before every shift, proper re-sharpening depending on use roughly weekly to monthly. More reliable than any fixed schedule is the test: if the knife cuts through a ripe tomato without pressure, it is sharp enough.
Is an electric knife sharpener bad for the blade?
Modern devices with guided grinding angle operate gently and remove only little steel. For daily kitchen use they are the most practical solution, as every team member achieves consistent results without practice.
Can I sharpen serrated knives?
Not sensibly with a honing steel — but suitable pull-through sharpeners like the Bartscher MS310 also sharpen serrated edges. Heavily worn serrated edges belong to the sharpening service.
Why do my knives get blunt so quickly?
Most common causes: cutting on hard surfaces (stainless steel, glass, stone), loose knife in the drawer, dishwasher instead of hand washing — and missing daily honing. Just a cutting board plus honing steel routine doubles edge retention noticeably.
