I was rummaging through a bag of shaving stuff in my closet and came across this old pack of blades that I didn't recognize. I believe it was thrown in with some brush handles I purchased at auction in 2013. The brand of the blades is Sealskin Blue Steel Blades, made by a company named White River Paper Mills, Inc out of Indianapolis. Googling the brand and company yielded zero results. This may be my first time researching something where google did not have a single reference. Has anyone heard of these blades?
