Got a link, brand, or model number for these "science" grade blades? I've been an on-and-off DE shaver for some years, and I've never heard of this option. I settled on Feather blades myself.
I guess they're taking about American Personna Super blades, which are commonly referred to as "Lab Blues". They're about 12 cents a blade when you buy them in packs of 100, which makes them one of the cheapest blades around.
There's lots of discussion on shaving forums about exactly why they're called "labs", but as far as I know they're just regular double-edge blades.
I also prefer Feather. They cost about twice as much, but work much better on my tough stubble.
It wasn't stated that the blades were necessarily better, but the fact these "science grade" blades were chosen over name brands implies there may be some benefit. This was totally new to me, and it sparked my curiosity.
