Workshop Heaven Hand Stitched Threesquare Rasp 150mm No.4 (38tcm)


Used for working small flats, cutting grooves and forming acute internal corners down to 60 degrees, the triangular section and finely toothed corners of the threesquare rasp makes it a versatile favourite.

Working into the groove at the top of a 3D heart shape for example, or undercutting a lambs tongue detail. The last third of the rasp is tapered, so it can also work a groove into a flat surface.

  • Shoulder to tip: 150mm
  • Overall length: 290mm approx
  • Face width: 9mm tapering to 5mm at the tip
  • Coarseness: 38 teeth per square cm (medium)

Each Workshop Heaven hand stitched rasp begins life as a forged and annealed blank of high carbon tool steel is carefully ground and ‘fined’ to a smooth surface before being strapped to a soft anvil to have their teeth individually raised or ‘stitched’ one by one with a special punch and a curved filemakers hammer. 
 The handles are turned from English walnut with brass ferrules to a 200 year old Holtzappfel pattern, individually fitted and set by hand for a comfortable, elegant and secure grip.

Rasp Care
In order to keep your rasps clean and free from corrosion we recommend removing any clogging from the surface with a stiff bristled brush and applying a few drops of metalguard ultra liquid corrosion inhibitor after each use. Store your rasps in such a way that they cannot touch or rub against each other.
