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.

德國鋼 1.4116 因其合金成分中含有鉻、鉬和釩,被廣泛用於廚刀及餐具,具備良好的耐腐蝕性、耐用度與易於研磨的特性。然而,相較於高端刀鋼,其碳含量較低,因此在某些廚刀應用上未必理想。較低的碳含量限制了鋼材可達到的最大硬度,進而影響刀刃的保持性。這意味著,雖然 1.4116 鋼刀能夠磨得很鋒利且抗鏽蝕,但比起高碳鋼製刀具,可能需要更頻繁地磨刀。

    德國鋼
    14.0% 10.5% 7.0% 3.5% 0
    C Carbon 0.5%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.
    C
    0.5%
    Cr Chromium 14.0%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.
    Cr
    14.0%
    V Vanadium 0.1%
    Forms extremely hard carbides for superior edge retention. Also refines grain structure, improving toughness.
    V
    0.1%
    Mo Molybdenum 0.5%
    Improves hardenability and toughness. Boosts corrosion resistance and helps the steel hold hardness under heat.
    Mo
    0.5%
    Mn Manganese 1.0%
    Aids hardenability and strength. Acts as a deoxidiser during smelting. Excess can reduce toughness.
    Mn
    1.0%
    Si Silicon 0.5%
    Strengthens the steel matrix and acts as a deoxidiser. Improves hardness and resistance to oxidation.
    Si
    0.5%
    P Phosphorus 0.02%
    Impurity from the smelting process. Even small amounts cause brittleness — steelmakers keep this as low as possible.
    P
    0.02%
    S Sulfur 0.01%
    Impurity that reduces toughness and promotes brittleness. Intentionally added only in free-machining steels.
