Hand Putty Knife Manufacturer – FLONPRO
Ningbo Tongque Machinery Manufacturing Co., Ltd. (FLONPRO) is an export-oriented Hand Putty Knife manufacturer with 15 years of expertise in power tools and hand tools. Operating a 10,000 sq.m. facility near Ningbo and Shanghai ports, we produce a full range of putty knives, scrapers, and multi-function tools for construction, painting, and surface preparation. Our annual export volume of US$5–10 million reflects consistent quality and reliable supply to global distributors, hardware chains, and industrial buyers.
We supply stainless steel and carbon steel putty knives in widths from 1 inch to 6 inches, with handle options including PP/TPR, beech wood, and full-tang designs. Every tool is manufactured under end-to-end quality control—from raw material inspection to final function testing—ensuring straight blades, secure handle attachment, and corrosion resistance. We support OEM and ODM customization for blade shape, handle color, branding, and packaging.

Application Fit and Workpiece Considerations
Our putty knives are designed for surface preparation in construction, painting, and renovation. Typical tasks include:
- Applying and smoothing spackle, joint compound, or filler on drywall and plaster.
- Scraping old paint, adhesive, or wallpaper from walls, wood, and metal.
- Cleaning excess caulk or sealant from joints and corners.
- Opening paint cans, prying lightweight materials, or mixing small batches.
Blade material selection depends on the workpiece: stainless steel resists rust and is preferred for wet compounds or outdoor use; carbon steel offers higher edge retention for heavy scraping but requires oiling to prevent corrosion. Flexible blades (0.5–0.8 mm) suit spreading and finishing, while stiffer blades (1.0–1.2 mm) are better for aggressive scraping.
Critical Specifications and Quality Control
Every putty knife we produce is checked for:
- Blade straightness: No warp or bend across the full width.
- Edge grind: Uniform bevel angle for clean scraping without gouging.
- Handle attachment: Secure rivet or full-tang construction to prevent loosening.
- Surface finish: Mirror polish or satin finish per specification; no burrs.
- Hardness: Typically HRC 48–52 for carbon steel blades; stainless steel at HRC 42–48.
We implement in-process inspection and final sampling per AQL standards. Custom specifications (e.g., special blade length, ergonomic grip, or color) are documented in the engineering drawing before production.
Configuration Options and Customization
As a Hand Putty Knife supplier, we offer flexible configuration to match your market requirements:
- Blade: Stainless steel (201, 304, 420) or carbon steel (SK5, 65Mn). Thickness from 0.4 mm to 1.2 mm.
- Handle: PP, TPR, wood (beech, rubberwood), or full-tang with riveted scales.
- Width: 1", 1.5", 2", 2.5", 3", 4", 5", 6". Custom widths available.
- Packaging: Blister card, clamshell, hang tag, bulk box, or custom retail packaging with your branding.
- OEM/ODM: We develop tools per your drawings or samples, including color, logo, and special features like magnetic tips or multi-function heads.
Automation Integration and Tooling
Our putty knives are manual hand tools and do not require electrical or pneumatic integration. However, we can supply complementary items such as Hand Tools (e.g., scrapers, spatulas, and trowels) for consolidated sourcing. For high-volume users, we offer bulk packaging and private labeling to streamline distribution.
Quality Assurance and Compliance
We follow a documented quality management system. Each production batch is tested for:
- Dimensional accuracy (blade width, length, thickness).
- Edge sharpness and uniformity.
- Handle grip strength and ergonomic comfort.
- Corrosion resistance (salt spray test for stainless steel).
Our tools comply with international safety standards for hand tools. Certificates of conformity are provided upon request. We also perform pre-shipment inspection with photos and reports.
Installation, Maintenance, and Serviceability
Putty knives require no installation. For maintenance:
- Clean blade after each use with a dry cloth; for carbon steel, apply light oil to prevent rust.
- Sharpen edge with a fine file or stone when dull.
- Store in a dry environment; avoid dropping to prevent blade bending.
We supply spare parts (handles, blades) for replaceable-blade models. Technical documentation and handling instructions are included with each shipment.
Information We Use to Configure Your Solution
To prepare a precise quotation and sample, we need the following project details:
- Target market and typical application (e.g., drywall finishing, paint scraping).
- Preferred blade material (stainless steel or carbon steel) and hardness.

- Handle material and shape (ergonomic, wood, or full-tang).
- Estimated annual quantity and packaging format.
- Any branding, logo, or color requirements.
- Target price range and delivery port (FOB Ningbo or Shanghai).
With this information, we can provide a tailored product specification, sample lead time, and commercial terms within 2–3 working days.
