I have Sabretooths, semi-pro (heel bail with toe loop), and they fit in this just fine. I even have the long center bar on them.

Since no one else has answered your question I will try to help. I don't have the saber tooth crampons however I have the Petzl Dart and Petzl Vasak and they both fit fine in the bag with room to spare. Looking at the pictures I don't see why it wouldn't fit. You might check the Black Diamond Toolbox, it might be bigger.I'm pretty happy with this bag, its pretty light, protects my pack and its vented so I can spray a little wd-40 on my crampons when I get home and store them in the bag. If the truth be told there really aren't many solutions for carrying crampons...
