>>7194131I enjoy shaving with them. It's a bit of a morning ritual for me.
Apart from that, I find their history and engineering interesting. The reason I collect them is because I want to shave with every single safety razor ever made and feel how different they are. It's a pretty unrealistic goal, but so far I have 127 different ones. I also collect and restore shaving brushes, to a lesser degree. It's a pain to replace the knots. Working with glue and all...
My favourite razor is the Gillette Slim Adjustable. In my opinion it was the peak of safety razors before they kinda fell into obscurity. Nowadays they've seen a bit of a renaissance. My favourite modern safety razor is the Parker Variant.
