to this day,there is not one single domestic manufacturer of mass produced shave soap,de blades, or razors on the north american continent as far as i know.all available are from other countries or artisan made.the exception is personna med prep blades i believe.but again they are technically for med prep.dove men is also a british product.on the simplest terms,it is the artisan who has stepped up to the plate to give us choices to our shaving routine,though carts and goo are still king for most shavers..
i put some distilled water or purified drinking water into my brush mug, put brush in, do my shower and eat. Perhaps it gets 30 minutes of soak time. That is all. Then i lather up and shave. That portion normally takes me 5 minutes if i take my time. Even if i use my other hand, it still takes under 10 minutes.
Traditional shaving products disappearing from grocery stores does not mean that fewer people use them. It could simply mean that the sales have moved to Amazon and other online stores. If that happened, wetshaving could have grown by leaps and bounds and we wouldn't notice it. In fact, it looks like traditional shaving has gone from being a niche online hobby to becoming mainstream. The evidence? Look at all the shaving gear available. It is many, many orders of magnitude greater than 20 years ago, or even 10 years ago.
I've been using Dove Men+Care 3 in 1 Shave Soap and find it better than the Dove bath soap. Lathers fast, very good long lasting, thick, hydrating, slick soap. I find it just as good if not better than Cella or Vito's, About the same lather as Tabac but different scent. The scent is not top notch but quite pleasant and at $1.37 per bar in an 8 pack is not a bad price point. I just grate a bar on the back of my grater and press it all into my favorite ceramic bowl, lasts a few months.
Don't forget the Med Prep's stable mate, the Lab Blues, recently renamed to AccuForge. Both blades made in Verona, Virginia. Other than that, I agree with your comment.
