Thanks in advance for any help on this. Attached is a photo of a (supposedly) Very Soft tip. When I started to shape the tip with a new Lenox titanium blade, it made the sound of a trowel scraping across a brick!! As you will notice, it DID NOT ribbon like other tips. In fact, I would say it powdered. I store tips in a humidor to keep them from drying out. I only use Lenox blades to cut them down and shape. Did I get a mislabeled tip? Unfortunately, I've had this happen several times with this type of tip. Thanks for any suggestions.
