12 months use from a cartridge?

That's quite a claim.

I'd also be interested to know where he found cartridges that were sharp in the first place.........

I get 30 shaves from cartridges without even trying.

Others on this forum have posted the same.

That's pretty sharp.

Pretty sharp, or pretty durable?

I regularly use cartridges which were stocked for over 15 years. No special measures, and no sign of corrosion either.
