Replacement Blades for Dead Ringer Brodheads

Does anyone know where to get replacement blades for either the Dead Ringer Trauma or the Super Freak Extreme X-Bow broadheads? I have searched the internet. Tried to email Dead Ringer. Tried to call Dead Ringer. There were very few Dead Ringer replacement blades on the internet and none for the broadheads I use. Dead Ringer didn’t respond to me emails and their phone number doesn’t seem to work. The company seems to still be in business. I have had great experiences with the Dead Ringer Trauma, but I am about to switch to broadheads with available replacement blades.
