Putting the hammer down ... on my hand

While I'm making slow progress on taking down my chimney,
at least so far it's been just a Band-Aid/ibuprofen job. I was using just a
large hammer and chisels in an attempt to be more controlled, what with being
thirty feet in the air and all, which was too slow but still worked -- until
the chimney liner started cracking at its first seam. Getting the top three
feet of chimney liner down in one piece was an adventure, but I didn't want
shattered ceramic shards all over the lawn ... I could describe what I did, but
you'd all just lecture me. In any case, that's been the most dangerous part so

However, I just brought home a sledgehammer, so that could change.
