Call me a cynic when it comes to vintage razor brand name reputations. All I do know is that the vintage Puma I have shaves as well as the lesser known vintage brands of Solingen razors I also have. In other words they all shave very well. I think the standards were pretty high for all Solingen makers back in the day as competition was fierce among the many makers. Anyway to me a Puma is a good razor.
I'd also take what a maker of a product says in praise of their product in a self produced booklet with a large dose of salt.
