Knives are the most used tools in any commercial kitchen and also the most common source of laceration injuries. A well-maintained, sharp knife is both safer and more effective than a dull one. Dull knives require more force to cut, increasing the chance of the blade slipping and causing injury. This guide covers knife maintenance practices that keep blades in optimal condition along with the safety protocols that prevent injuries.
Proper knife care also directly affects food quality. Clean, sharp cuts produce better presentation, more consistent portion sizes, and less bruising of delicate ingredients.
Understanding the difference between sharpening and honing is the first step toward proper knife maintenance.
Honing realigns the edge of a blade that has bent or folded during use. A honing steel does not remove metal. It straightens the microscopic edge of the blade back to its proper alignment. Honing should be done before every use or at least at the start of each shift. Hold the steel vertically with the tip resting on a stable surface, then draw the blade down the steel at a 15 to 20 degree angle, alternating sides with each stroke. Six to eight strokes per side is typically sufficient.
Sharpening removes metal to create a new edge. Sharpening is needed when honing no longer restores cutting performance. Frequency depends on use, but most commercial kitchens sharpen knives every one to two weeks. Methods include:
Signs a knife needs sharpening:
Edge maintenance between sharpenings extends the time between full sharpening sessions. Always use the correct cutting board material. Hard surfaces like glass, marble, and metal damage edges rapidly. Wood and high-density polyethylene boards are the best choices for edge preservation.
Every kitchen team member who handles knives should be trained in these fundamental safety practices.
Carrying knives through the kitchen requires specific technique. Hold the knife at your side with the blade pointing down and slightly behind you. Announce your movement by saying "Knife" or "Sharp" so others know to give you space. Never carry a knife in a way that points the blade toward anyone or conceals it from view.
Cutting technique affects both safety and results. Always cut on a stable cutting board with a damp towel beneath it to prevent sliding. Keep your non-cutting hand in a claw position with fingertips curled under, using knuckles as a guide for the blade. This technique protects your fingers while maintaining precise control.
Passing a knife to another person should always be done handle-first with the blade pointing away from both people. Alternatively, place the knife on the counter and allow the other person to pick it up.
Rules that prevent knife injuries:
Designated knife areas in the kitchen help prevent accidents. Knives should have specific storage locations and should not be left on prep surfaces where they can roll off or be knocked.
How you store knives affects both blade condition and kitchen safety.
Magnetic knife strips mounted on the wall keep knives visible, accessible, and separated. The blade edges do not contact other surfaces, preserving sharpness. Mount the strip at a height where knives are easy to reach but above the normal work surface to prevent accidental contact.
Knife blocks protect edges and keep knives organized. Choose blocks with horizontal slots so knives rest on their spines rather than their edges. Clean the inside of knife blocks regularly to prevent bacteria growth in the slots.
Knife guards or sheaths protect blades during transport and when stored in drawers. Plastic blade guards are inexpensive and prevent knives from damaging each other or cutting someone reaching into a drawer.
What to avoid:
Personal knife kits are common in professional kitchens. Each cook maintains their own knives in a knife roll or case. This promotes accountability for knife condition and eliminates disputes over whose knife is whose.
No matter how well-designed your kitchen is, one food safety incident can destroy years of reputation overnight.
Kitchen management is where food safety lives or dies. Every piece of equipment, every temperature reading, every cleaning protocol either protects your customers or puts them at risk.
Most food businesses manage safety with paper checklists — or worse, memory. The businesses that thrive are the ones that make safety visible to their customers.

Cleaning protocol:
Between different food types, knives must be cleaned and sanitized. Cutting raw chicken and then using the same knife on vegetables without proper cleaning transfers pathogens directly. Color-coded knife handles help enforce separation between raw proteins, produce, and ready-to-eat items.
Wooden-handled knives require extra attention. Wood can harbor bacteria in cracks and grain patterns. Inspect wooden handles regularly for splitting or roughness, and replace knives with compromised handles.
A formal knife safety program reduces injuries and creates a culture of care in your kitchen.
Elements of an effective program:
Track knife-related injuries to identify patterns. If most cuts occur during a specific task or at a particular station, you can implement targeted prevention measures.
How often should kitchen knives be sharpened?
Most commercial kitchens benefit from weekly sharpening. High-volume prep operations may need more frequent sharpening. Honing with a steel should be done before each use to maintain the edge between sharpenings.
Are cut-resistant gloves required in commercial kitchens?
Requirements vary by jurisdiction. Even where not mandated, cut-resistant gloves are recommended for tasks involving repetitive cutting motions, working with mandolines or slicers, and cleaning knives. They significantly reduce the severity of cut injuries.
What is the best cutting board material for knife edge preservation?
End-grain wood boards are the gentlest on knife edges, followed by edge-grain wood and high-density polyethylene plastic. Avoid glass, marble, ceramic, and metal cutting surfaces, which dull knife edges rapidly.
Should each cook have their own personal knife set?
Personal knife ownership promotes better knife care and accountability. Many professional kitchens require cooks to provide their own knives. If the kitchen provides communal knives, designate specific staff members responsible for maintenance.
