ものの、硬度面の不足と、研ぎなおしか効かないという
実用上の難点が存することを否定しえない。Although carbon steel knives have good initial sharpness, there is a problem in that long-term use causes chemical corrosion or abrasion of the cutting edge, which impairs durability. On the other hand, although stainless steel cutlery does not have the disadvantage of chemical corrosion, it cannot be denied that it has practical drawbacks such as insufficient hardness and resharpening.

なお、切れ味の鋭利性を必ずしも充分には満足しきれな
い、という欠点が存する。Recently, attempts have been made to construct cutlery from ceramic materials, and some have already been commercialized into products such as scissors. Although knives made of this type of ceramic material have significantly improved durability compared to those made of conventional steel materials such as JAM steel or stainless steel, they still do not necessarily maintain sufficient sharpness. The drawback is that it is not completely satisfying.
［問題点を解決する為の手段 コ
