How to Find Reliable Putty Knife from China in 2025


China remains a leading manufacturer of high-quality putty knives, offering competitive prices and durable products.

What Buyers Should Know Before Buying Putty Knife from China


When sourcing putty knives from China, consider factors like material quality, handle ergonomics, and blade flexibility.

Additionally, verify the supplier's minimum order quantity (MOQ) and shipping terms to avoid unexpected costs.

  • Flexible Blade Knives: Ideal for spreading compounds smoothly.
  • Stiff Blade Knives: Best for scraping and removing old paint.
  • Angled Blade Knives: Perfect for reaching tight corners.
  • Wide Blade Knives: Suitable for covering large surfaces quickly.

Functions and Features of Putty Knife


A putty knife is primarily used for applying and smoothing fillers like spackle or joint compound. Key features to look for include a comfortable grip, rust-resistant blade, and the right flexibility for your task.
