Oh yeah? Well, I can get my Magnus heads so sharp when I wave a freshly sharpened head over my arm, the hair leaps off my arm in sheer terror.

(First liar never stands a chance, Matt.[8D])

I really don't remember the last time I used a replaceable blade head, but I do know they were Muzzys. I can buy a half dozen good cut on contact heads for 1/3 the cost of 3 replaceable blade heads. Then I can sharpen them over and over again, instead of shelling out even more money for replacement blades. Call me a cheapskate if you like, but I prefer the term economist.
