I took another look at it & tapped lightly on the chuck with it pointing down. Eventually the piece of blade did fall out. No harm to the chuck, the blade had bent slightly at the hole for the chuck pin. This was holding the blade stub in. I think this is a good testimonial to the quality & durability of Milwaukee tools. As a professional electrician, I use these daily without let down. Expensive yes, quality, durability too. Thanks.
