I must be doing something wrong. I have been a regular user of Wool Fat shaving soap for a couple of years now and have been very happy with it, no matter what razor/blade combination I am using it gives me a clean, close and well cushioned shave. After reading several rave reviews of Tabac Shaving Soap here and elsewhere I purchased a puck a couple of weeks ago and began using it. It lathers well (though not any better than my Wool Fat) but shaving with it has been a disaster. It is as reliably awful as my Wool Fat is reliably good. Again, no matter what the razor/blade combination, if feels as if my blade is grabbing each whisker and pulling it out of my face by its root. It turns even my normally efficient ATT Aluminum SE1 into an unimaginably inefficient shaver requiring multiple passes in all directions. Has anyone else experienced this with Tabac and if so were you able to fix it and how? Clearly a YMMV experience.
Hard to say what might be happening. While I truly enjoy the Fat, I find Tabac a very excellent performer indeed. I strive for a BBS shave everyday, but not always without paying a price. When I have a particularly bad day, I generally follow up the next day with Tabac as it is so slick and protective for me that it gives my face a chance to recover with no further irritation. If your successfully lathering MWF I'm sure you are properly lathering Tabac with perhaps one caveat. Perhaps you might need just a few more drops of water with Tabac as I find it a fairly thirsty soap that soaks up moisture during the shave. Tabac can seem to dry on the face if not hydrated quite enough and that may be what may be causing your blade to seem to drag. Tabac is one soap that for me performs well with any style brush, any of my razors or blades just as you said you experience with MWF. Certainly a mystery for sure. I should add that I primarily am a bowl latherer. I have tried over 85 brands over the last 5 years and Tabac is definitely in my top 20 and would be even higher if the post shave performance was better. Tabac is one of those soaps that would more than please me if it was the only soap produced.
