It's great for knocking nails if you have good aim

Remember to get someone else to hold the nail ! :~)

thank you for showing me this weapon now i can reenact my plans of making furniture

Only if you want that 'distressed look' :~)

That's disappointing ! :~(

it could still hammer nails if you were good enough

Watch those fingers ! :~)

This is amazing, now I can murder TWICE as fast

Or twice the victims in the same time ! :~)

What if you made it double sided

Even quicker ! :~)
