I've used ordinary bath soap to shave with. I've used a dedicated shaving soap or tow in my lifetime as well. NOTHING matches this! My razor felt like it was taking orders from me to give the best possible shave. No nicks, no cuts. My skin seemed to be massaged by the soap and razor. After shaving, 12 hours now, my skin STILL feels smooth, smells great, as tho I'd used a lotion or massage bar since shaving.
I have a good old fashioned shaving mug and a shaving brush, and I hardly had to lather it up at all. This bar will last, I have no doubt. And I still feel smooth long after shaving. For those like me who use a classic double-edged, single blade safety razor, we know that with the right technique (and a good soap!), your shave will last longer, and be smoother with less grow-back than any of those fancy 'multi-blade' razors on the market.
I highly, HIGHLY recommend this to anyone. Oh, and women can use it too. :)
