This is my second. The first one lasted me 16 years and was still good until it was lost. I'm a carpenter by trade, but that doesn't mean I haven't peeked, demonstrated, and pulled nails with this thing. I really offended this little guy. Sometimes I adjusted the head carefully and sharpened the claws again with a belt. It was hard to work without it and I was so happy to have one in my pockets again!
