I use mainly Feathers and normally toss them away after 3 shaves (with 3 passes) in combination with my soaps where I'm looking for good cushion. (triple milled soaps and/or tallow soaps)
But now I can extend the life of the blade with min. 1 shave when I use Proraso on the fourth shave and still get the same comfortable and close shave I get with a new blade in combo with Tabac for example.
So for all the people who normally toss their blades after 3 times when used with soaps which delivers comfortable cushiony lather, try a fourth shave with Proraso if you have it and see if you can an extra good shave out of your blade.
Note: It will probably work as well for certain creams and (glycerin) soaps that deliver a lather with the same characteristics as Proraso but I don't have them.
