Recently purchased so I haven't got a chance to go through all 20 blades but on my first few shaves with this set I had to go through 4 different blades off the bat due to inconsistent sharpness or the blades. Some were not sharp at all, I could run my finger across it no issue. Another, half of the blade was sharp and the other half was dull. Can't complain for the price but not sure if this is a common issue or if I got unlucky with this batch.

I am using these in a vintage Eversharp razor. The shave is as good as the Supply razor using the Supply blades, perhaps a bit better.

The supply co blades irritated my skin. This is the only other brand I have tried. No skin irritation with these blades. They are sharp.
