Adopting the Safety Razor.
For more than a decade I was happy with a Gillette Mach 3. I used it every day for years. Eventually I found an affordable electric razor so I switched to that, and used it until I had to replace the blades at least twice. I only reduced my use of it because the blades became dull. That’s when I started to experiment with a bamboo razor, a Gillette Glide, and finally safety razors.
