Parker 91R is a three-piece double edge safety razor. It means you have three separate pieces: the cap, the base and the handle. Assembling the razor is easy, but I find the two-piece design to be a little bit more comfortable. It has also scalloped safety guard.
The handle is made out of brass and covered with chrome. This is rare for a razor in this price range. Brass doesn’t corrode so this good. But! The head is still made out of pot metal also known as Zamak, and unfortunately, this is usually the part that starts showing signs of corrosion first. I wouldn’t worry too much though. All Merkur razor, for example, are also made out of pot metal. And with proper care will last many many years. At the end of the day, these items are not family heirlooms but tools to be used to look cleanly shaven.
While the razor looks pretty, some have reported blade alignment problems, meaning the blade protrudes asymmetrically. This adds to the risk of cutting your self. All safety razors in this price range usually have some quality issues from time to time. And what kind of product wouldn’t have when it is mass produced? Should you happen to get one of these razors that has this problem, then contact the seller. Parker kindly replaces the faulty devices.
