Focus on the core aspects of "tool purpose, material to be processed, and cost budget" – even beginners can accurately match:
Step 1: Determine the direction based on usage
Food / food ingredient contact: Prioritize DLC coating, nitriding treatment, mirror polishing; avoid industrially toxic coatings
Metal / hard plastic processing: Choose TiAlN coating, diamond coating, or carburizing treatment
Cutting hard materials / impact resistance: Nitriding + laser strengthening (heavy-duty knives), shot peening (thin-blade knives)
High-speed cutting: Edge 钝化 + TiAlN coating for better anti-shedding and durability
Step 2: Find the right fit based on material
Stainless steel knives: Nitriding, DLC coating, passivation polishing (avoid carburizing)
Cemented carbide knives: TiAlN/diamond coating, laser strengthening to supplement toughness
Low-carbon steel knives: Carburizing + quenching to improve wear resistance
Thin-blade knives: Shot peening + passivation to prevent edge curling and chipping
etStep 3: Choose cost-effectiveness according to budg
Only high cost-effectiveness is practical! Specify your usage scenario in the comment section, and we will directly match you with the most cost-effective plan~
