You move them forcefully over parts and areas that you want to be smoother.
You could use a plane. You could use a lathe. You could use rasps and files, too.
That's an 'opinion thing', like "are Chevy's better than Fords" , but I honestly believe Nicholson files and rasps in general are VERY good products and I consider Benchmark average.
Files are categorized into six roughness levels based on the coarseness of their teeth: Coarse, Medium, Fine, Extra Fine, Dead Smooth, and Rasps. Coarse files have the largest teeth and remove material quickly, while fine files have smaller teeth for smoother finishes. Extra fine and dead smooth files are used for precise finishing and polishing. Rasps are typically used for shaping and removing material from wood or soft materials.
Rasps and files are hand tools that are used for smoothing and shaping of metal and wood when other edge cutting tools won't do the trick.
They're called wood "Rasps".
The boy grasshopper has rasps on his hind legs, he rubs those rasps across his body and it makes a sound that the girl grasshoppers can hear.
Femoral rasps are surgical instruments used during orthopedic procedures, particularly in total hip arthroplasty (hip replacement surgery). They are designed to shape and prepare the femoral canal to receive the femoral component of a prosthetic joint. These rasps typically feature a textured surface to facilitate bone removal and ensure a secure fit for the implant. Their use is crucial for achieving proper alignment and stability of the hip prosthesis.

They use .wav files but the files can be converted to MP3's if need be.
Various hand saws, aves, axes, mallets (as opposed to hammers--nails being rare), clamps for gluing, horsehide glue, dowel-makers (plug cutters), chisels and knives, carver's platform, spinning wheel lathes, a huge variety of files, rasps, and bastards.
People used various tools to stone carve, including chisels, hammers, mallets, and rasps. Chisels were used to cut and shape the stone, hammers and mallets were used to strike the chisels, and rasps were used for smoothing and refining the surface of the stone.
The essential stone working tools needed for sculpting and shaping stones effectively include chisels, hammers, rasps, files, and sandpaper. These tools are used to carve, shape, and smooth the stone to create intricate designs and sculptures.
