Woodcutting

Woodcutting is one of the two publicly-available skills, the other being Mining. Players with high levels of woodcutting will get higher drop rates, which can make farming more efficient.

Tree Feller
Tree Feller is a Gatherer-only ability which allows for an "AoE" woodcutting effect. Instead of only chopping the log being targeted, Tree Feller allows the player to take out other logs, saplings, and leaves within a certain radius depending on skill level.

Leafblower
Whenever any player reaches level 100 woodcutting, if they tap (not hold down) their mouse on a leaf block, the block will disappear and there will be a 10% chance of dropping a sapling. This can be a good way to get saplings quick, and remove leaves quickly.

Double Drops
For every skill level the player has in Woodcutting, they have an additional 0.1% chance of getting a double-drop from each log harvested. This only works on naturally born trees, not logs placed from your inventory, planks, or others. Trees created through bonemeal will yield double drops.
