But do not despair! It can be fixed and rather easily as you can see in the video and slideshow above.
I use a dull blade most of the time and then when I send blades in for refurbishing I send the one with the broken tab in to be repaired.
Always have a platform on hand in either a dull blade or a new platform and you will never worry about a broken tab again. Replacing the platform backing on a Bravura blade can save you a lot of money. It's easy to do it yourself.
