The Fusion ProGlide and Fusion5 ProGlide are the same blades. Just the names are different…Both Mach3 or Fusion cartridge razors offer a good clean, no-frills shave. Fusion cartridges yield a closer shave and have a longer ‘shave’ life which is reflected in the purchase price. Should you want the closest, most luxurious wet shave, then consider using a safety razor.There’s a lot of precision, engineering and artistry that goes into each one. Making a great blade is an art. This precision of its design is the main reason why razors are so expensive. To make them, it all starts with fine sheets of steel that are ground so they’re super sharp to the tip and sturdy at its base.
