It's difficult to determine who the best woodcutting skiller in Old School RuneScape is, as skill levels can change frequently and there are many players who may not be well known but have a high woodcutting level. However, some players who are famous for their woodcutting skills and achievements include "Elvy" who reached level 200 million experience in woodcutting and "Outsanity" who holds the record for cutting the most magic logs in a 24 hour period.
