I have tried and do like double edge shaving, but it is not a thing I can do every day before heading out to work, very time consuming.
Like most blokes I am always on the look out for an alternative to the expensive Gillette cartridge razors. I have tried a lot, spent way to much trying all comers.
These are the three I kind of rate.
Cornerstone. Cornerstone have a new cartridge and have had to redesign their razor. Though the new blades are sharp the the actual shave is not that close and takes several passes to achieve anything you want to leave the house with. This razor sadly is more style over function.
King of Shaves. King of Shaves will not be winning any design awards with this one. Seems to use the same cartridge as the Gruum system. Offers a close shave. Though after the third shave the blades seemed to dull quite quickly.
The one out of the three that I would recommend is the King of Shaves. Close shave and very very cheap.
But like most blokes I will pick up Gillette when they are on offer in the shops, sorry it is the best cartridge razor out there.
