Anymore blades it'll start looking like the grill of an old Chevy Nova.

I'd be willing to give it a try.

I was looking at my FUSION yesterday and with the five blades there's room in there for another blade without enlarging/widening the basic cartridge.  So the cartridge itself wouldn't be any wider/larger.

Nevertheless, the question remains......WHEREFORE DOST THOU DRAWETH THE LINE?

Man that's nuckin' futs.  Just ridiculous.  It's like KC said, more blades don't equal a better shave.  I actually have blown, way too much I don't care to get into, money to experiment with different blades to find my niche.  I shaved with the Mach 3, Shick Extreme, Fusion, and just an ordinary knock off double blade.  One got just about as close as they other.  I have to say that the knock off was a little rough on the dome though but as far as closeness is concerned you're just wasting your money for dishing out the bigger bucks for a bunch of extra blades.  I'm not trashing the Fusion.  It is a decent razor but just to bulky for me and for the cost of the blades I can get the same result with a Mach 3 or Shick brand.  As a matter of fact I'm using the HB for the whole shave now and have been for a few months.  Saves a lot of money.  That's funny that this 6 blade thing was brought up.  I just seen a knock off version of this at a K-Mart a few cities over from me about 2 months ago.  It wasn't this certain one.  Like Nick said, this one probably isn't available here yet.  But the one I saw had a "Fusion" type look to it and came in a 4 or 5 pack.  And $hit you not, it had 6 blades.  I was like, "WHAT!!!"  Crazy.  Before too long they will come out with a 10 blade razor and if you want to use it you will have to get "Razor Blade Insurance."  You have to have something to cover you when you chop your head off while shaving.
