Gem SS PFTE Blades - On Average, How Many Shaves?

[GAW9576]

I just bought my first GEM razor, a Featherweight, and am excited to try it out today. I didn't have blades so I bought some PTFE coated blades on eBay. I only got 5 because I figure if I get 10 shaves per blade, it's going to be a while before I need more. I can also test whether I like the PTFE coated ones or want to try something else.

In any case, I always keep track so I'll make sure I count the shaves for each blade. I have pretty soft facial hair and also a round beard so only shaving my cheeks and neck. That means I should get many more shaves per blade I assume.

Like this?

Now that takes skills.
