Woodcutting is the 3rd skill and can be unlocked by crafting an Axe. Each tree provides logs which can be sold or used as fire for the Cooking Skill. Experience is gained when chopping down the tree. Research perks will give the chance of more experience per tree as well as providing roots which can be sold for extra money.
Even though the statement on the axe "For each upgrade, gain double the amount of logs you get when chopping trees." is implying a multiplicative upgrade, the upgrades in fact do not work in such a fashion. Only the first upgrade is multiplicative which gives double the amount of starting logs as stated. Each upgrade after the first is an additive upgrade resulting in receiving 3, 4, 5, etc.. times the starting logs with each respective upgrade.In other words if the starting logs are equal to 100% then each upgrade adds additional 100% logs resulting in 200%,300%,400%,500%, etc... total logs received depending on the current upgrade level.
You can also increase the XP from trees and get shiny trees for more logs and roots with their respective research perks.

Notes:
These mostly have to do with the upgrade potion.
- Using an upgrade potion on a fruit tree also works.
- If you use an upgrade potion on a shiny tree, the upgraded tree will be shiny as well
- You can not upgrade the same tree twice
- Each blue axe orb will give you +50 logs per tree
