ROLLINGDOG 12 Inch Knockdown Knife
The 12-inch knockdown knife is designed for controlled texture creation in smaller areas. It features a flexible acrylic blade that extends 11.4 inches from the handle, offering a wide 12-inch working width. The textured rubber grip provides comfortable control, and an aluminum bridge inside the housing connects the blade to the handle for stability.

Cautions: the acrylic blade may show wear with heavy use; avoid forcing the blade through extremely hard compounds.

The plastic blade is noted for durability and easy cleaning, with compatibility for extension poles. Best for: professionals or DIYers working on larger surfaces who want consistent patterns and minimal blade maintenance. Cautions: while flexible, the blade may eventually wear with repeated use on very rough textures.

A tempered aluminum bridge keeps the blade straight, supporting stable large-area texture work. Best for: users who need a long-reach, durable tool for expansive walls and ceilings.

Buying Guide
What should you consider when choosing a knockdown knife?
- Blade material and flexibility: Acrylic and Lexan blades offer flexibility for even knockdowns; choose polycarbonate options for durability in larger jobs.
- Blade width and length: Shorter blades provide precision in small rooms; longer blades cover large surfaces more quickly but require steadier handling.
- Pole compatibility: If you plan to reach high walls or ceilings, confirm Acme-threaded extension poles or compatible threading for your setup.
- Grip and control: A rubberized handle improves comfort on long sessions and reduces hand fatigue.
- Build stability: A solid bridge or frame (often aluminum) helps keep blades straight and maintains uniform texture patterns.
- Texture type and technique: For knockdown textures, ensure the blade can create natural patterns without excessive scratching or gouging.
- Maintenance: Look for blades that are easy to clean and replace when needed to preserve texture quality over time.

Yes, acrylic or Lexan blades are standard and provide the required flexibility for knockdown textures; ensure the blade is properly supported by a stable bridge.
Plastic (acrylic) blades are flexible and reduce marring; metal blades may offer durability in heavy-use scenarios but can be less forgiving on delicate surfaces.
Extension poles are optional but recommended for reaching high walls or ceilings; many models are designed to thread onto Acme poles.
