I was so shocked at the price of these cartridge blades, I had to take a photo of it. I used to use one of these blades per week when I still used cartridge shaving blades. A pack of eight blades will fill my car’s tank with petrol. I can see why wearing beards has become more popular!
In contrast, Double Edge (DE) blades, even by Gillette, cost only R4 ea. That is 27x cheaper! I actually normally use the Astra Superior Platinum blades at R17.99 per pack of 5 blades. But if we want to compare with “cheap” DE blades, then it is about R10 per pack of 5 blades.
Apart from just cost, it becomes a real no-brainer to be using DE blades for shaving, when you also consider they can be recycled, and a single blade is better for prevention of ingrown hairs than multi-blade cartridges.
