Stanley 11-525 High-Carbon Steel Double-Edge Carpet Knife Blades 5-Pack

The Stanley 11-525 High-Carbon Steel Double-Edge Carpet Knife Blades 5-Pack is a specialized floor-covering replacement accessory engineered for precise carpet cutting, pad trimming, and flexible textile shearing. Manufactured from high-grade carbon steel with a 0.015-inch blade thickness and a 2.25-inch (57.15 mm) overall length, these straight-edge blades feature dual razor-sharp cutting edges to maximize cutting life per blade unit. Designed to fit Stanley carpet knives and most standard commercial carpet tools, this 5-piece carded set ensures rapid material penetration and clean edge alignment during floor installation projects.

Best Used For:

  • Carpet & Underlayment Installation: Executing clean seam cuts, wall trimming, and foam padding sizing during residential or commercial flooring installations.
  • Flexible Floor Covering Fitting: Slicing sheet vinyl, linoleum, and heavy rubber flooring underlayment with high edge control.
  • Industrial Textile & Canvas Shearing: Cutting dense woven fabrics, heavy canvas tarps, and synthetic felt underlayment on assembly sites.

Key Performance & Safety Features

  • High-Carbon Steel Alloy: Heat-treated carbon steel construction maintains keen edge retention under continuous friction against abrasive carpet backings.
  • Reversible Double-Edge Profile: Dual cutting edges allow flooring contractors to flip the blade over to utilize a fresh cutting point immediately.
  • 0.015-Inch Precision Gauge: Engineered blade thickness ensures smooth material shearing without binding or dragging through thick carpet fibers.
  • Universal Carpet Knife Fit: Standardized mounting slots ensure complete compatibility with Stanley carpet knives and standard flooring cutters.
