old model ... but the best blade for shaving.

Indeed, these are the blades Gillette Sensor simplest, swivel head, 2 twin blades individual springs, lubrastrip plate and ... that's all;
for me, this model together the best of technology, everything you need where you need and nothing superfluous.

I tried other models of blades but I always came back quickly to these, because I virtually never cut myself with.
Even the next generation, Gillette Sensor Excel with additional small rubber plate shave less to my taste.

As for models 3, 4 or 36 blades ... impossible to shave properly in hard to reach places, such as the nose or to be precise on the edge of the legs.

In short, the model Gillette Sensor blade is perfect in my opinion but obviously the stupidity of the consumer society has struck again despite the success of this model, it will no longer manufactured, probably not profitable enough because too effective, marketing prefer objects with planned obsolescence.
