You know, power attacks don’t feel right for harvesting tools (wrench, ratchet, impact driver) because of the animation. It looks like you’re just whacking the target instead of harvesting it, so I don’t expect to get resources beyond what I’d get wailing on the target with a pickaxe. I wonder if others feel this way: that a power attack should still look like you’re manipulating the target to extract useful parts, for visual communication reasons.As for bone knives, there’s an added trick to harvest faster. Aim at the air above the target when pressing the power attack button. You’ll trigger the ‘power melee attack’ stabbing animation, instead of the ‘harvesting power attack’ animation, which is a slower slicing across motion. So long as you aim to hit the target when the knife lands, you’ll harvest it the same either way. You can harvest a deer in one second this way.
