Engineering and Verification Protocols

Every KatoriForge prep board starts as raw titanium plate sourced from certified mills. We do not use cast scrap or secondary melts. Raw stock undergoes initial ultrasonic thickness mapping to ensure a uniform 2.0 mm profile across the entire sheet, followed by CNC laser profiling to cut dimensions to within a 0.2 mm variance.

The Science Behind the Build

Raw titanium requires strict surface stabilization before it enters a kitchen. We utilize mechanical satin finishing followed by an automated laser chamfer pass along the perimeter.

• Quality check: Technicians inspect every board using surface roughness testers to verify an Ra value between 0.6 and 0.8 micrometers, followed by a 40-point visual scan for micro-inclusions.
• Traceability: Mill test certificates accompany each heat lot, documenting iron, oxygen, and nitrogen limits to guarantee Grade-1 compliance.

Why This Matters for Daily Use

Tight manufacturing controls eliminate the three most common prep board defects: rocker wobble on flat stone countertops, rough edges that cut fingers during handling, and acid staining from garlic or vinegar. Natural metal passivation creates an inert titanium oxide layer that never leaches, peels, or degrades under thermal shock from boiling rinse water.
