I honestly hate reviews that start with "I haven't used it yet...", but, alas, here we are.  I have not used this yet, but I purchased it thinking I needed it at the time.  The reviews on this are exceptional, from those that have used it.  It has remained in my tool bag for all the jobs I've been to, and I know that when the time comes, it will perform as expected.  It's heavy, solid, the edges are sharp.  It's all you need for a step bit.
