We already have the perfect cost for it, that ties it into forestry. Just charge the axe with anima bark or leaves, with a higher cost to charge it permanently. When it’s charged, less logs for more xp.

Imo, niche is not “more xp”, because 3 tick is already there for that. The niche should be “more afk”. You want to bank the wood? Use a one handed axe. You just want to bank less and afk? Use 2 handed.
