440C Stainless Steel Bar Stock – Made in USA
Features: Premium 440C stainless steel with high carbon content, annealed and precision ground for easy stock removal and machining, offering excellent edge retention and wear resistance. Delivered in the annealed state to minimize warping during grinding and shaping.
Best for: Knife makers and machinists who need a ready-to-work bar stock with consistent tolerances and strong edge-holding properties. This option suits production or custom blade makers who value material reliability and a USA-made supply chain.
Caution: The annealed state is softer than hardened 440C; expect to heat-treat and temper for performance blades to reach maximum hardness.
440C Stainless Steel Barstock for Knife Making – 1/8″ x 1-1/4″ x 12″
Features: Premium grade martensitic 440C stainless steel with approximately 17% chromium, 1.1% carbon, and balanced alloying elements. Dimensions are 1/8″ x 1-1/4″ x 12″.
Best for: Knife blades requiring a compact stock with solid corrosion resistance and good edge retention for small-to-medium sized projects.
Caution: The smaller cross-section may limit bevels and grind removal for very heavy stocks; plan machining passes accordingly.
440C Stainless Steel Barstock for Knife Making – 1/4″ x 2″ x 12″
Features: Premium grade martensitic 440C, high-carbon alloy with 17% chromium, 1.1% carbon, and other alloying elements. Dimensions are 1/4″ x 2″ x 12″.
Best for: Medium-thickness blades where substantial stock is needed for aggressive grinds or plunge lines, with solid wear resistance and corrosion protection after tempering.
Caution: Heavier stock means longer grind times; ensure equipment can handle the material weight and heat generation during sharpening.
440C Stainless Steel Barstock for Knife Making – 3/16″ x 1-1/2″ x 12″
Features: Premium grade martensitic 440C stainless steel with high carbon and significant chromium content; designed for knife blades. Dimensions are 3/16″ x 1-1/2″ x 12″.
Best for: Builders seeking a balance between edge retention and ease of grinding with adequate thickness for performance blades and tools.
Caution: As with other 440C bars, post-heat-treatment hardness will depend on tempering; plan heat-treat steps to achieve desired hardness.
Texas Knifemakers Supply 440C Barstock – 1/8″ x 1-1/2″ x 12″
Features: Premium martensitic 440C stainless steel barstock for knife blades; alloy composition includes 17% chromium, 1.1% carbon, 1% manganese, 1% silicon, and 0.17% molybdenum. Dimensions are 1/8″ x 1-1/2″ x 12″.
Best for: Beginners and intermediate makers who need a manageable stock size with reliable corrosion resistance post-temper and grind.
Caution: The stock’s annealing state may require careful handling during initial grinding to maintain flatness and avoid warping.
Buying Guide
Practical questions to help you choose the right 440C bar stock:
- What blade thickness and grind style will you use? Choose thicker stock (like 1/4″ x 2″) for robust blades and heavy grinds; thinner stock suits finer lines and detailed work.
- Is edge retention priority? 440C is known for good hardness after proper heat treatment, which supports edge holding in knives and tooling.
- How easy is it to machine or grind? Pre-annealed stock is easier to work; plan tempering and surface finishing after shaping.
- Do you need USA-made material? If supply chain and origin matter, consider U.S.-made bars for consistent quality and availability.
- What is your corrosion resistance requirement? 440C offers substantial corrosion resistance when properly hardened and tempered, similar to other high-carbon stainless steels.

FAQ
- What is 440C best known for in knife making? It is a high-carbon martensitic stainless steel with good edge retention and wear resistance after proper heat treatment.
- Should I anneal 440C before grinding? Annealing improves machinability and reduces warping during initial stock removal; temper after shaping to reach desired hardness.
- Is 440C suitable for beginner makers? Yes, especially in smaller or standard-sized bars; offers a forgiving balance of grindability and performance after tempering.
- Does 440C have corrosion resistance comparable to other stainless steels? Yes, it provides strong corrosion resistance, particularly after hardening and tempering, though not immune to corrosion under harsh conditions.
- Which size should I start with for practice blades? A lighter, smaller cross-section (like 1/8″ stock) is recommended for practice and learning the grinding process.
- What should I consider when selecting a bar stock brand? Look for consistent dimensions, annealed condition for easy machining, and a reputable supplier with reliable material composition.
