In https://philip.greenspun.com/blog/2019/01/24/gillette-versus-dorco-shaving-test-2/ the one thing that seems to give Gillette a slight boost over the Korean-made Dorco blades is that flexible head on the Gillette handle.
What if one could buy third-party blades and put them on the Gillette handle?
Schick offers just such a product: Hydro Connect. I ordered some yesterday and will be offering a report!
(These seem to be tough to obtain from retailers, though it is easy to buy them direct from Schick. I’m wondering if retailers are afraid of getting entangled in litigation, e.g., “P&G’s Gillette sues Schick maker Edgewell over razor blade design,” which notes that “Procter & Gamble Co’s (PG.N) Gillette unit on Monday sued the maker of Schick razors for the second time in 13 months, seeking to stop its sale of razor blade cartridges designed to fit Gillette’s Fusion handles.”)
