Around 700. I go through one a week, so these should last until I'm about 74.
Hmm, I'm probably going to live into my early 90s. Maybe I better stock up!
I have less than 100, but I'm still new in the whole DE game. Planning to get a supply of Derbys next time I order something. I need to order some feathers to try out just to see if they are as good as everyone says.
Wow! Currently 37% of people have less than 100 blades. I will warn you now, you are running dangerously low. If the Shavepocalyse occurs and cartridges take over your days of smooth BBS shaves will be numbered.
I have about 180-190 blades in total:
120 or so Feathers
20 or so Red Personas
10 or so Derbys
10 Astra Superior Platinums
25 Franklins "No Frills" Stainless Steel Razor Blades, not bad value actually I bought 10x10 packs @ $1.99 ea when the local Franklins became IGA, the boxes are marked "Product of USA" and "Satisfaction Guaranteed". They perform about the same as the Wilkinson Swords that Coles sell for $10.95.
