Do All Dorco Razor System Handles Fit All Dorco Cartridges?

Yes, all Dorco razor systems and cartridges on the website with the exception of the Pace Comfort Thin II (TNA3006) are interchangeable. You’d be able to use a 4 blade razor handle with a 3, 4, 6 or 7 blade razor cartridge. This works for all systems and cartridges on the site -- both men's and women's.
