Core Responsibilities

Primary Functions

Execute a thorough initial assessment of each blade to identify nicks, chips, broken tips, and the overall condition of the edge and steel.
Select the most appropriate sharpening methodology and equipment—including Japanese whetstones, belt grinders, or guided rod systems—based on the knife's steel type, intended use, and condition.
Skillfully establish and reprofile the primary bevel of the blade, correcting any geometry issues and setting the foundation for a superior edge.
Meticulously refine the cutting edge by progressing through a sequence of increasingly finer abrasives to achieve a razor-sharp, durable, and polished finish.
Expertly hone and strop the final edge to remove the microscopic burr and precisely align the apex, ensuring maximum sharpness and cutting performance.
Perform intricate blade repairs, such as reshaping broken tips, grinding out significant chips, and thinning the blade to restore original cutting geometry.
Service a diverse array of bladed instruments, including but not limited to professional chef's knives, single-bevel Japanese cutlery, serrated bread knives, grooming and industrial scissors, and various workshop tools.
Maintain precise and consistent edge angles tailored to the specific application, from acute 15-degree angles for slicing to more robust 22-degree angles for chopping.
Conduct standardized sharpness tests, such as slicing through newsprint or delicate food items, to verify the quality of the finished edge before returning to the client.
Ensure all knives and tools are thoroughly cleaned, sanitized, and safely packaged before and after the sharpening service, adhering to food safety standards.
Methodically maintain and calibrate all sharpening equipment, including dressing and flattening whetstones, replacing abrasive belts, and ensuring machine accuracy.
-- Provide expert, consultative advice to clients on best practices for knife storage, daily maintenance (honing), and proper usage to extend the life of the sharpened edge.
Handle high-value, custom, and sentimentally important cutlery with the utmost care and precision to prevent any cosmetic or structural damage.
Develop specialized techniques for challenging blades, such as concave shear edges, serrations, or blades with complex curves and grinds.
Execute advanced finishing requests, including creating a kasumi finish on Japanese knives or achieving a full mirror polish on the bevel.
