...with the current price of the multi-blade cartridges , the cost of a good plain Davo pays for it’s self in a few months.
Guys have to remember the original safety razors by King Gillette gave the holder away for free because the prime business was the continued sale of blades...until one died and and even after for the final shave by the mortician, who likely used a Gillette safety razor.
I’ve been using the same multi-blade cartridge for weeks. There’s no need to throw one away after just a few uses.
When you’re shaving and the blades start to pull, run the face of the cartridge down your arm in the opposite direction you would use it to shave. Do this ten times. It is like stropping a straight razor. The cartridge blades will be refurbished and sharp again. This can be repeated over and over, each time the razor gets dull, saving you a ton of money on cartridges.
