Stalgast 300 mm Knife Sharpener for Professional Kitchens

A manual knife sharpener restores a keen edge by drawing the blade across fixed abrasive rods set at the correct angle. The rods remove a controlled amount of metal, creating a fresh bevel that meets the original factory geometry. This method ensures consistent results without the skill needed for a freehand stone, making it practical for busy kitchens where multiple chefs handle the same knives.

The operator places the sharpener on a stable worktop, secures it with a non-slip base if provided, and draws the knife blade through the slots in a single smooth motion. Each slot corresponds to a different grit, starting with a coarse abrasive to reshape the edge and finishing with a fine one to polish it. The process takes only a few passes, allowing rapid turnaround between services.

Constructed in black plastic housing, the unit measures 300 mm in length, fitting neatly alongside other prep tools. The abrasive rods are standardised to produce an edge hardness of 52-54 HRC, matching the temper of most professional kitchen knives. This hardness range balances sharpness retention with resistance to chipping, ensuring the blade performs reliably through repeated use.

The compact size and straightforward operation make it suitable for placement near the prep station, reducing downtime when knives lose their edge during service. No power supply is required, so it can be positioned anywhere on the worktop without needing a socket.

Cleaning involves wiping the housing with a damp cloth and removing metal particles from the abrasive rods with a stiff brush. Regular maintenance prevents build-up that could scratch the blade or reduce sharpening efficiency.
