For some time, I’ve tried to avoid multi-blade razors because they’re very bad at creating sharp edges such as at the end of sideburns or mustaches. Also, they often are difficult to clean when one hasn’t shaved for three or more days because the hairs get stuck between the blades.
However, I’ve now discovered Gillette Fusion which not only has five blades; it also has access to the back of the five blades, making it feasible to flush out all hairs, and it has an extra single blade on the other side for precision shaving.
It’s not perfect, but it’s the best razor I’ve used yet. Nice.
