Why do my imported grass shears rust despite being coated?

Rust usually occurs if the factory applies the PTFE or paint coating over improperly cleaned steel, or if the coating is too thin (under 15 microns). Edges also rust where the coating is ground away during final sharpening. Applying a light machine oil post-sharpening at the factory is essential.

What is the difference between single-blade and double-blade action?

In single-blade action, one blade remains stationary while the top blade moves. In double-blade action, both blades move toward the center. Double-blade shears offer cleaner cuts and reduce grass binding, but require a more complex pivot mechanism and cost slightly more to produce.

Can I use my own brand colors for the TPR handle grips?

Yes, factories can match exact Pantone colors for the TPR overmold. However, custom colors usually require meeting the higher end of the MOQ range (typically 3,000 pieces) to justify the plastic resin batch size.

Sourcing grass shears at scale requires balancing blade metallurgy, handle ergonomics, and the durability of the swivel mechanism. For B2B buyers, the challenge isn't just finding a factory that can assemble a garden tool; it is ensuring consistent heat treatment and precise blade alignment across thousands of units. Poor tempering leads to rolled edges, while loose assembly tolerances result in blades that chew grass rather than cutting it cleanly.

Blade Metallurgy and Hardness Specifications

The core of any grass shear is the blade material. Buyers must specify the exact steel grade and required hardness (measured in HRC) to match their target market, whether it is a budget consumer line or a professional landscaping tool.

Material	Typical Hardness (HRC)	Application & Characteristics
65Mn High-Carbon Steel	48 to 52	Entry-level to mid-range. Good edge retention but requires anti-rust coating.
SK5 High-Carbon Steel	50 to 54	Professional grade. Excellent sharpness and wear resistance; industry standard for premium shears.
420J2 Stainless Steel	45 to 49	Consumer grade. High corrosion resistance, ideal for damp environments, but requires more frequent sharpening.

To prevent rust and reduce cutting friction, high-carbon blades (SK5 and 65Mn) are typically finished with a non-stick coating such as PTFE (Teflon), hard chrome plating, or black oxide. Chrome plating offers superior durability against abrasive soil, while PTFE provides the lowest friction for clean cuts.

Manufacturing Tolerances and Quality Control

The defining feature of modern grass shears is the multi-position swivel mechanism, which allows the user to rotate the blades (often up to 360 degrees) for horizontal trimming or vertical edging. The locking detents in this mechanism must withstand repeated use without developing play.

If the pivot bolt is under-torqued, the blades will splay apart when cutting thick grass. If over-torqued, the spring mechanism will fail to reopen the blades smoothly. Catching these issues requires rigorous quality control during assembly, not just prior to shipping.

Critical QC Checkpoints for Grass Shears

HRC Verification: Batch-testing blade hardness to ensure heat treatment consistency.
Gap Inspection: Checking against light to ensure zero daylight between the closed blades.
Swivel Lock Integrity: Cycle-testing the rotation mechanism to ensure detents do not wear out prematurely.
Spring Cycle Testing: Compressing the return spring for 10,000+ cycles to check for fatigue or failure.
Grip Adhesion: Testing the bond between the PP (polypropylene) core and TPR (thermoplastic rubber) overmold on the handles.

Customization and OEM Production

For brands looking to differentiate, grass shears offer significant room for customization through OEM/ODM services. While the blade stamping dies are often standard, buyers frequently invest in custom injection molds for the handles.

Ergonomics play a major role in user fatigue. Specifying a lightweight aluminum lower handle with a soft-grip TPR overmold can elevate a standard shear to a premium price point. Additionally, buyers can customize the blade lock mechanism—single-handed thumb locks are heavily preferred in Western markets over traditional wire loops.

Buying Mechanics: MOQs, Pricing, and Lead Times

Hardware hubs in Zhejiang and Guangdong provinces dominate garden tool manufacturing. Before conducting factory audits, buyers should align their volume expectations with typical factory requirements.

1,500 - 3,000

Typical MOQ (Pieces)

Per colorway/design for OEM packaging.

35 - 45 Days

Standard Lead Time

From deposit and sample approval to shipment.

$1,200 - $2,500

Handle Tooling Cost

For custom plastic/TPR injection molds.

Pricing is heavily influenced by steel commodity rates, the complexity of the swivel mechanism, and the type of blade coating. Upgrading from a basic black oxide finish to a premium PTFE coating typically adds a marginal cost per unit but allows for a significantly higher retail margin.
