Minor Annoyances (Because Nothing Is Perfect) ❌ Doesn’t Swing Itself – Unfortunately, manual effort is still required. No self-hammering technology… yet. ❌ Too Nice for Just Smashing Things – If you’re looking for a pure destruction tool, this might actually be too well-crafted for reckless demolition.
