When shaping and smoothing materials with a surform plane, blade condition directly affects performance. The Stanley STA521398 Surform Blade 140mm 5½in Fine Cut is a genuine replacement blade designed to restore cutting efficiency and maintain smooth, controlled material removal.
Manufactured to fit compatible Stanley Surform block planes, this flat fine-cut blade provides consistent rasping action across a wide range of materials. The precision perforated design allows material to be shaved away efficiently while reducing clogging during use.
The fine cut configuration is ideal for applications requiring a smoother finish compared to coarse blades. It removes material in a controlled manner, making it suitable for finishing work and detailed shaping tasks.

This versatility makes it particularly useful for carpenters, joiners, kitchen fitters, installers, and maintenance professionals working across mixed materials.
The 140mm (5½in) blade length ensures compatibility with Stanley Surform block planes of the corresponding size, including metal body models. Replacing worn blades regularly helps maintain efficiency, reduces user effort, and improves overall finish quality.
Compared to using dull or clogged blades, fitting a new fine-cut blade restores optimal cutting performance, ensures cleaner shaping, and reduces surface tearing.
