Hardness
Rockwell C Hardness (HRC) measures how resistant a steel is to permanent deformation. For kitchen knives:
55–58 HRC — Soft. Easy to sharpen and forgiving of rough use, but dulls faster. Typical of most German knives.
59–61 HRC — Balanced. Good edge retention with manageable sharpening. Common in mid-range Japanese knives.
62–64 HRC — Hard. Excellent edge retention, holds a very fine edge. Requires more care and a fine stone to sharpen.
65+ HRC — Very hard. Exceptional edge longevity but more brittle — more prone to chipping if used roughly.
Higher is not always better — it depends on how you use and maintain your knife.

V特2號（V特２号，V-Special 2）是武生特殊鋼對經典日立青紙二號鋼的詮釋。作為一種合金碳鋼，其化學成分與青紙二號非常接近，並額外添加釩元素，加上武生宣稱的更高純度，V特2號的耐磨性應該比青紙二號略有提升。
V特2號具備極佳的淬硬性，可達到 HRC64，許多製刀師會利用其高硬度製作極薄刀身，能非常順利地切割食材。武生也生產夾有銅或青銅層的夾鋼材料，因此 V特鋼也常見於歐美刀匠的作品，讓許多廚師都能體驗碳鋼刀的極致切割感受。
