About Chrome Vanadium Steel
This is an alloy steel with added chromium and vanadium. Chromium increases hardness, and vanadium improves toughness (resilience/flexibility).
It has the characteristic of maintaining high wear resistance and stable high hardness through good heat treatment.

About Acetate Resin
Acetate resin is a plant-derived resin, making it gentle on the skin, less likely to cause allergic reactions, and environmentally friendly due to its biodegradability.
It has high transparency, moderate flexibility, and is supple and difficult to break.
It also has oil resistance, making it strong against oils.
