China Cnc Knife Paper Knives Sharpening Machine

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Sharpening: Equipped with diamond and carbon steel surfaces for restoring razor-sharp edges on kitchen knives.
  • Multi-Grit Sanding: Three perforated metal cards (400#, 1000#, 1200# grit) enable progressive sharpening, from coarse edge restoration to ultra-fine polishing.

Key features

  • 1. Material Technology: Diamond-Coated Abrasives & Corrosion-Resistant Steel

    • With diamond-coated abrasives and corrosion-resistant carbon steel, you can achieve precision sharpening that outlasts traditional sharpeners*. The durable steel body ensures longevity even in frequent use, while diamond grits maintain sharpness over time.

  • 2. Interactive Design: Multi-Grit Perforated Cards for Versatile Handling

    • The perforated metal cards offer flexible, lightweight handling, making it easier to navigate tight spaces or detailed work compared to rigid sharpening stones. With grits ranging from 400# to 1200#, you can select the perfect abrasiveness for coarse to ultra-fine sharpening.

  • 3. Performance Parameters: Wide Grit Range for All Sharpening Needs

    • With a grit range from 400# to 1200#, you can sharpen knives from dull edges to razor-sharp finishes in a single tool—eliminating the need for multiple devices. This outperforms single-purpose sharpeners by ~30% in versatility*.

  • 4. Scenario Solutions: Dual-Use for Home & Commercial Settings

    • Designed for both home kitchens and professional environments, this sharpener ensures consistent performance for daily tasks or high-volume use. The lightweight, perforated design reduces fatigue during prolonged use compared to bulkier models*.

  • 5. Certification Standards: Eco-Friendly Materials & Sustainable Design

    • With eco-friendly materials and a stocked supply chain, you can reduce waste and ensure reliable availability. The carbon steel and diamond components align with modern sustainability standards for responsible tool manufacturing.

Supplier's note

  1. Technical Breakthroughs:

    • Diamond-Coated Edges: Triple the abrasion resistance of traditional steel sharpeners, extending tool lifespan by 40%.
    • Perforated Design: 20% lighter than solid steel models, reducing user fatigue during prolonged use.
    • Grit Range System: Covers 95% of knife sharpening needs, eliminating the need for multiple tools.

  2. Version Selection Guide:

    • Base Model: Best for home users needing occasional coarse sharpening (e.g., repairing chipped edges).
    • Advanced Model: Ideal for culinary professionals requiring medium-fine polishing (e.g., sushi chefs).
    • Pro Model: Chosen by industrial users for ultra-precise finishes (e.g., surgical tool maintenance). With its 1200# grit, it outperforms industry benchmarks by achieving a 0.5-micron surface finish—critical for high-end blade applications. Pair its diamond coating with the perforated design to ensure minimal material waste during sharpening.
