I know there is a separate section for safety razor blades, but I felt like I would have better luck asking the specific SE guys this question rather than going to that section. I know that some of the carbon steel SE blades are very usable, but was wondering if anyone has tried the GEM Micromatic "Reversible" blades in the yellow container. I have a few of them, but have been hesitant to try them. Anyone shed some light on them? Thanks
