We have already tested all Ensō collections by bringing them in the carry-on/cabin luggages across multiple major international airports and there has been no issue at the security check points. Since Ensō collections do not have pointy blade, it will not be regarded as a danger to the public, therefore safe to bring onboard an airplane.
We use pure titanium ions interacting with active nitrogen atoms to form the gold colour coating, and pure titanium ions interacting with C2H2 (Acetylene gas) to form the black coating via PVD – Physical Vapor Deposition process (both are non-toxic, environmentally friendly, ultra durable and titanium based coating).
