Stainless Steel
"Stainless" means stain-resistant, not stain-proof. In kitchen use, the steel can still discolour or pit if exposed to acidic environments — citrus, vinegar, or salt water — for extended periods. Wash and wipe dry after every use, and avoid leaving the blade soaking in water. With basic care, a stainless knife is very low-maintenance and a great everyday choice. 타케후 특수강, 일본

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.

VG5 강은 높은 굽힘 강도, 항복점, 연신율, 단면 수축률 및 충격 강도를 포함한 우수한 기계적 특성으로 알려진 고급 스테인리스 커틀러리 강재입니다. 정제되고 불순물이 적은 조성 덕분에 연삭성이 향상되고 열간 단조가 용이합니다. VG5는 크롬(Cr)과 탄소(C) 함량이 높아 일반적인 스테인리스 강 등급을 능가합니다. 이러한 조성은 공정 탄화물의 결정화를 억제하고, 균형 잡힌 원소 비율과 정제된 탄화물의 균일한 조직을 통해 경도를 극대화하는 데 도움이 됩니다. 이 강재는 제조 과정에서 세심한 정제 공정을 거쳐 불순물을 최소화하고 최적의 입자 조직을 달성하며, 전략적인 열처리를 통해 더욱 개선됩니다. VG5는 VG2에 비해 탄소 및 몰리브덴(Mo) 함량이 높고 바나듐(V)이 추가되어 더 미세한 탄화물을 형성합니다. 이러한 조합은 경도, 내마모성 및 내식성의 탁월한 균형을 보장하여 VG5를 가정용 주방 도구용으로 특히 인기 있게 만듭니다.
