Brand Usage Disclaimer (Non-Infringement Notice)
All brand and machine names listed above are used only to identify compatibility and replacement purposes. SHJ KNIFE is not affiliated with the original manufacturers. We produce high-quality aftermarket replacement shear blades, not genuine OEM parts.
OEM & Reverse-Engineering Capabilities
Right after confirming machine compatibility, many customers choose SHJ KNIFE because they need OEM-level replacement work, especially when the original manufacturer no longer supplies parts. We support:
- OEM production for machinery manufacturers
- Reverse engineering from a worn blade sample
- Custom builds when drawings are missing
- Legacy blade reproduction for discontinued machines
Our engineering team rebuilds precise measurements and improves performance by selecting stronger tool steels or upgraded heat treatment profiles. This allows us to deliver reliable blades even when machines are decades old.
We offer blade solutions tailored to the specifications of each machine, including custom dimensions and mounting configurations. If you require a replacement for a specific resurfacer model, our engineering team can assist in matching the right blade for your setup.
*Disclaimer: We are not affiliated with or endorsed by any of the brand names listed above. All references are for compatibility purposes only.
Metal Shear Blades Material & Specifications
We select steel grades and specifications based on your cutting force, production volume, and metal characteristics. This ensures your blade resists wear, holds an edge, and stays structurally stable.
Available Tool Steel Grades
We use tool steels known for strength, toughness, and wear resistance:
D2 / SKD11 – general shearing with high wear resistance
Cr12MoV – stable hardness for most sheet metal applications
H13 – strong toughness for high-impact shearing
6CrW2Si – ideal for long production runs
High-carbon high-chromium steels
Tungsten alloy tool steels (optional for extreme workloads)
Hardness Range
We tune hardness to fit each application:
HRC 50–55 – for impact-heavy cutting
HRC 56–60 – for general sheet metal work
HRC 60–65 – for thin sheet or light-duty precision cutting

We list only a portion of the available blade sizes here because the full range includes many variations. If you need a different size or a custom specification, we can produce it according to your requirements.
Custom Metal Shear Replacement Blades
When customers struggle to find blades for rare or discontinued machines, we step in with flexible custom manufacturing. You can send us a drawing, a dimension list, or even a dull blade. We measure the critical points, reproduce the shape, and improve the steel selection if your cutting workload requires a stronger blade.
Customers who manage multiple machines often choose us to help unify their blade specifications. This reduces sourcing complexity and cuts long-term replacement costs.

FAQ About Metal Shear Blades
Q1. Can you produce blades for very old or discontinued machines?
Yes. We reproduce blades for old or discontinued machines through our drawing archive or by reverse-engineering your worn blade. If the original OEM no longer exists, we can still build a fully compatible replacement that matches your cutting workload.
Q2. What materials can your metal shear blades cut?
Our blades handle many types of metal, including carbon steel, stainless steel, aluminum, copper, galvanized sheets, and metal alloys. If your material has special hardness or coating, we recommend a suitable tool steel and hardness level to support clean, consistent cuts.
Q3. Do you accept small orders or one-off replacement blades?
Yes. We support one-off replacements, small batches, and large production runs. Many customers order a single blade for machine repair or testing before placing larger orders.
Q4. How long is the production lead time?
Most orders take 7–25 days depending on blade size, steel grade, and quantity. If you need urgent delivery, we offer fast-track production for common shear blade models.
Q5. What information do you need to quote a replacement shear blade?
You can send us one of the following:
- A drawing
- Key dimensions
- Machine brand and model
- A worn blade sample
Even a simple measurement list helps. Our team confirms the rest.
Q6. What is the typical hardness for metal shear blades?
Hardness depends on your cutting load. Most blades fall between HRC 50–65. We adjust hardness to match your material thickness and the force of your machine to avoid edge chipping and premature wear.
Q7. How do I choose the right steel grade for my shear blade?
D2 or Cr12MoV works well for general sheet cutting. H13 and 6CrW2Si perform better in high-impact applications like billet or bar cutting. If you share your material type and thickness, we recommend the best matching steel grade.
Q8. What is the expected service life of your shear blades?
Service life depends on cutting load, steel grade, hardness, maintenance, and material thickness. Most customers see a noticeable increase in blade life compared to their previous replacement blades, especially when switching to our performance-matched steel and heat treatment options.
Q9. Do your blades fit the same mounting holes and geometry as the original part?
Yes. We match hole size, spacing, bevel angles, thickness, and every mounting detail. This ensures the blade installs smoothly and works exactly the way your machine requires.
Q10. Can you improve performance compared to my original blade?
Yes. Many customers upgrade to stronger tool steels or adjusted hardness levels to reduce wear and get cleaner cuts. We can suggest improvements based on your cutting workload.
Q11. Are your blades genuine OEM parts?
No. We supply aftermarket replacement shear blades that fit OEM machines. All brand names are used only to show compatibility.
