This large Nakayama Akapin Tomo can be used either for direct hand held honing or as a slurry creation medium (Tomo). This Akapin would be considered the most aggressive, pre finishing Tomo of the set. If used in a honing progression, this would be used first for its high cutting speed and larger particles which remove the previous grit scratches effectively.
