This truly amazing tool has become my most used (and cherished) handtool.  For delicate interior work, it is perfect for removing brads and small nails.  You can easily avoid wood dings and mars by placing a solid plate (or the end of a second identical tool) under the pry head.  The flat end gives you a very thin (and sharp! be careful) edge which allows you to wedge in between moulding and trim and pull them apart.  It's not for demolition work, like a wonderbar, but I find more uses than I could ever have imagined for this fine, precision tool.  I bought an extra one for my neighbor, and he has come to same conclusion regarding its usefulness.  Don't leave home on a job without it!
