I switched to shave soap and brush back in June. I was still using a Mach 3, then I tried the fusion. Then so save some money I switch to the dollar shave club razor. Then I read that less blades are better. I was going to switch to a safety razor. I have tremors so I worried I would have problems. So I thought back to my fave razor of all time. The Trac II. Then I discovered the handles you guys sell. I found the perfect handle. Then I found these blades. I have been getting the best shaves that I have ever had. Even after 5 or six shaves with one cartridge I still get an excellent shave!! Almost no Knicks. Just where I have a bump. But I have my eye on a soap to help with that! I am never going back to a cartridge with more than too blades!
