A while I ago I got tired of buying these cartridges for my cartridge razor, some Gillette brand.
A pack of 5 blades were like 25 USD or 20 EUR.
A straight razor is about 100 USD or 80 EUR (for a good carbon steel 5/8") so I thought in four bladepacks I would have already paid the amount it would cost to get such a blade…
And that blade would last me a lifetime.
I like shaving with it more, oh the danger, especially when shaving the neck
The shave quality is also better. I usually just go with the grain first, then against the grain, instead of the “babybutt” WTG, XTG and then ATG full three pass shave, because I am lazy and my hair is not so super thick.
