Key benefits Provides controlled, repeatable blade finishing for consistent edge quality. Three operation options cover different blade types and setups, improving versatility. Builtin rails, guides, and knob adjustments help you work safely with the blade in hand. Uses an abrasive surface to refine and smooth edges, reducing the need for repeated manual sharpening. Designed for maintenance tasks in craft, hobby, and light workshop environments. What you need to know about compatibility and use Works with a holder and guide system that includes rails near the handle and a guide cabinet. Uses opposite guides and different strokes to produce even results across the edge. The procedure involves a series of controlled pushes and pulls, with 5–10 strokes per side depending on the method. Setup and use Method 3 Hold the holder with the leather blade facing up. Keep the blade edge pointed away from the leather. Push the back of the holder to raise the leather blade toward the working surface. Repeat this motion using the opposite guides, performing 10 alternating pulls. Exercise care with the blade in your hand. Usage 1 Place the flat side on the rail closest to the handle, so the blade rests on the abrasive surface. Push the blade away from the abrasive. Then repeat on the corresponding rail by turning the blade toward the abrasive and pulling it along the surface. Do this in alternating passes for 5–10 strokes. Method 2 Turn the knob so that the fine (smooth) side on the knob is raised. Place the flat on the guide cabinet so that the edge rests on the bar. Push the edge away from the abrasive, then move along the abrasive, alternating the edge toward and along the surface using the opposite guides. Perform 5 strokes on each side. Use scenarios Leatherworking tools: Regular maintenance of blades used in leather crafts to ensure clean cuts and long blade life. Precision cutting tools: Finetune edges on small knives or craft blades before detailed work to improve accuracy. Hobby and light workshop tasks: Quick edge refreshes on common blades used in model making, stencil work, or fabric cutting. Notes on performance The three methods are designed to accommodate different blade geometries and setups within the holder and guide system. Following the described stroke counts helps achieve uniform edge finishing and reduces the risk of overworking the blade. Always handle the blade with care and keep a firm grip during all steps.
