What is best in straight razor: hyper-edged, it shaves the hair without pulling, the three blades cover a large part of the face and limit the number of passes, and the lubricating strip slides the blade while giving an indicator wear (when it whitens, alongside the edge begins to dull and shaving becomes a little less nice). Good performance over time.
A tip: Do not leave unused strips to moisture, the lubricating strip may wear prematurely.
It's not the cheapest system, but this is clearly the most effective and most comfortable that I have tested. 5/5
