Okay folks I have an Idea !! ( I know , me having an idea could be dangerous ) !! Okay there is a blade called Jaguar Blades JT1 / JT3 / ORCA the blades say 62mm and the Durham blades measure about 60 mm but I think the jaguar are 62 including the ends that are like a DE blade that could be trimmed... The blades look like this... These blades were originally made by Dovo for their shavettes and are breakable but I believe if the tips were trimmed on the ends they would fit in the duplex and would probably be sharper than any other current blade for the Duplex razors.... What are you peoples thoughts? Might work or CRAZY idea?
