Polishing Knives

Polishing solutions for stainless steel surfaces

An even finish for stainless steel knives

Blade, bolster and handle place different demands on surface finishing. Osborn offers polishing buffs and compounds for an even finish, matched to the workpiece, initial surface and machine.

Blade, bolster and handle

Schematic of a knife blade being processed on both sides by counter-rotating polishing rollers

The illustration shows both sides of a blade being processed by counter-rotating polishing rollers. At the bolster, the thickened transition to the handle, the tool must also follow the contour.

Impregnated sisal cord tools are an option for decorated handles; folded sisal-cloth buffs suit plain surfaces. The handle geometry guides the choice.

Match the tool and compound

Buff construction, material and hardness determine contact with the surface. The compound is then selected for the required material removal and finish. Liquid polishing emulsions allow controlled dosing on automated equipment.

Match the process to your workpiece

Our application specialists help you assess the combination of tool, compound and machine. Trials under your production conditions support the choice. Find further polishing positions and technical details in the knife catalogue.
