Which file type is most appropriate for filing gaffs?

When it comes to filing gaffs, a smooth single cut file is the most appropriate choice due to its design and function. This type of file is capable of providing a fine finish on metal surfaces, which is essential for gaffs used on climbing equipment. A smooth cut allows for effective shaping and smoothing of the edges without excessive material removal or the risk of creating rough spots that could compromise the integrity and performance of the gaff.

The use of other file types, like rough double cut or coarse rasp files, would typically be more suited for aggressive material removal, which is not necessary for the fine-tuning needed on gaffs. These options may leave a coarser surface that could affect the gaff's functionality or grip. A flat file might be suitable for certain applications but does not offer the smooth finish required for the precise work needed on gaffs, making it less ideal compared to the smooth single cut file. Ultimately, the smooth single cut file ensures that gaffs maintain their necessary precision and safety for climbers.
