Not nearly enough, obviously... 

that would be easy for me: Four.I would like to see a follow-up that asks how many brands of DE blades do you have.
If you ever get tired of those, I'll take em.Some of my biggest holdings -
LB Wilks (100)
If you ever get tired of those, I'll take em.
I have about 2600 total blades as of today.
Did you by any chance get them off eBay a month or so ago? There was a batch of 100 that went for a bit. Worth every penny, in my opinion.Ha ha - sorry - took me WAY too long (and too much $$!) to finally get my hands on those few!
They are now my "special occasion" blades. Pull them out for celebration type events - Holidays, birthdays, milestones reaches, etc......
Now that is a respectable number.I have at Least 5000, not a seller or trader either....generations of blades if I threw them away daily !!!!![]()
