So that's over 700 shaves between honings. Is this on just clean strops? You may be a record holder. I get around 100 fairly regularly, I have one razor that went 131 shaves. I could have kept using it, but the toe was starting to dull when compared to a freshly honed razor.
Having a second razor is a good thing. Not only do you have a back up, but comparing the shaves against each other helps to keep your judgment calibrated.
