Different tools yield different quantities - check the table below to pick the right tool for the resource you need. Generally, a Pick favors meat while a Hatchet favors hide and secondary materials.
Estimates based on game-extracted data (weights, quantities, harvest multipliers, damage type chains). Each harvest event independently rolls each resource - higher weight = higher drop chance. Actual yields vary with RNG.
