I like trying everything, and the big news has been the use of DLC in many cheaper cartridges by companies such as Schick and Bic. It is very noticeable how much better those blades are in both performance and longevity while being an excellent value. The entire new Bic line is excellent (all the Flex and Comfort models), even if some are clearly better than others. Similarly the Exacta 2 by Schick (Atra clone) appears to have both DLC and Titanium coating and goes for about 10 shaves of good quality. I look forward to getting some DE blades with DLC, such as those by SuperMax. It is quite a contrast to try a very cheap cartridge system made by Kai without DLC, and see how much less good the shaving experience/value is, even though I felt the Kai disposables were a good value 5-6 years ago. The world of shaving is changing.
