Making rasps and rifflers
I have some cabinetmaker’s rasps in my kit, but they are the common machine-made kind. I have never used a hand-made rasp. Perhaps I should.
Rasps and rifflers are still made by hand in the old way by a few small manufacturers, like Forge de Saint Juery. The video below shows how much skilled handwork goes into making these tools, which explains why they are rather expensive. To justify the cost, it is claimed that hand stitched rasps work better and cut smoother than the machine made ones, as Chris Schwarz explains
The Forge de Saint Juery does not have a monopoly in this field. Another French maker is Liogier. There is a video shot in their factory too.
