I have tried many of the mass market soaps, gels, foams while perfecting the art of straight razor shaving and to date the best shave by far was with a tub of Wilkinson Sword soap in a blue bowl and for £1.49 I cannot grumble at all!

So if money is tight and you want a cheap shave then this is the best I think.
I must say it wont hold a thick foam but what it does do is leave a slick surface for the razor to glide over and I am sure with a couple of drops of glycerin it will as I have yet to try that.
