I doubt those Personna blades are US made. I think they are German.
US safety razor blade manufacturing ended awhile back, unless somebody has started again.
I use an Egyptian blade, Shark Platinum. Most days I use a vintage Gillette safety razor. Sometimes a Bic single blade disposable, but mostly the safety razor.
For me the key is to shave right after a shower or leave the soap and water on my face for a couple minutes to soften the beard.
Shaving this way has a zen like quality and satisfaction to it, much like tuning your own 1911.
I’m not saying you are incorrect, but everything printed indicates that is made the the US. Another Freeper posted a link about the company’s acquisition and it seems manufacturing may be in GA, but the individual blades say U.S.A. on the paper wrapper around the blade.
