Merkur ProgressDespite some favorable reviews -- most notably from Mantic59, a.k.a. the Sharpologist -- I was never motivated to get a Merkur brand Progress razor.
The reason for this is simple. I've used razors with chromed handles -- usually fluted -- and find them occasionally disturbingly slippery during shaves. So the many times that I've considered the Progress and its customized variations, I always eyeball that shiny chromed handle and say, no thanks; too much money, too risky a grip.
The other common objections: the plastic knob, the uncertain adjustment calibration, occasional blade-alignment complaints, etc., they don't even register in my awareness. I can't get past the potential slipperiness of the handle.
