Core Responsibilities

Primary Functions

Execute multi-stage grinding and polishing operations on knife blades and components using a variety of belt grinders, buffing wheels, and lapping machines to achieve precise, specified finishes such as mirror, satin, brushed, or stonewash.
Skillfully select, install, and dress the appropriate abrasive belts, buffing wheels, polishing compounds, and lubricants based on the material type, part geometry, and desired surface finish outlined in work orders.
Meticulously inspect blades throughout the finishing process, using both visual checks and precision measuring instruments like micrometers and calipers, to ensure dimensional accuracy, edge straightness, and cosmetic perfection.
Operate surface grinders and other machinery to precisely flatten and contour blade surfaces, ensuring they meet strict geometric tolerances before the final polishing stages.
Perform detailed deburring and edge-breaking on machined parts by hand or with specialized tools to remove sharp edges and burrs, ensuring safe handling and proper fit during assembly.
Interpret and work from complex blueprints, technical drawings, and work instructions to understand the specific finishing requirements, critical dimensions, and quality standards for each product.
Master the art of free-hand grinding and polishing, demonstrating exceptional hand-eye coordination and a steady hand to create consistent, flawless finishes on complex curves and surfaces.
Uphold rigorous quality control standards by performing final inspections on finished products, identifying and correcting any imperfections, blemishes, or deviations from the required specifications.
Maintain a comprehensive understanding of various steel types (e.g., stainless, carbon, Damascus, tool steels) and other materials to apply the most effective finishing techniques for each.
Set up, calibrate, and perform routine adjustments on grinding and polishing equipment to ensure optimal performance, consistency, and safety throughout the production run.
Consistently meet or exceed production quotas and deadlines without compromising the meticulous quality and high standards expected for premium products.
Adhere strictly to all company safety protocols and procedures, including the mandatory use of personal protective equipment (PPE) such as safety glasses, respirators, and gloves.
Maintain a clean, organized, and safe workspace to prevent contamination of materials and reduce the risk of accidents in a fast-paced manufacturing environment.
Document production activities, including parts completed, time spent, and materials used, by accurately filling out production logs and quality assurance forms.
Troubleshoot and resolve common finishing issues, such as uneven surfaces, swirl marks, or "orange peel," by adjusting technique, equipment, or materials.
Carefully handle and transport high-value, delicate components to prevent scratches, dings, or other damage at all stages of the finishing process.
Develop and refine techniques for creating specialized or custom finishes as required by new product designs or limited-edition runs.

Secondary Functions

Assist in the training and mentoring of new or less-experienced polishers, sharing knowledge of best practices, safety, and quality standards.
Perform basic preventive maintenance on polishing and grinding machinery, such as cleaning, lubrication, and belt/wheel replacement, to minimize downtime.
Collaborate with the engineering and design teams to provide feedback on manufacturability and suggest improvements to part designs for more efficient finishing.
Participate actively in continuous improvement initiatives, offering suggestions to enhance quality, increase efficiency, and reduce waste in the finishing department.
