I had picked up a pack of Astra Keramiks from Giovanni way back when. Just 5 blades. The first one was amazing, so I was hoarding the other 4. Then this forum (which I love, and am so glad you guys got it started) introduced me to Melyus, who has great prices and is a lovely man. Melyus carries these, so I just ordered a bunch and decided to go for another of the blades from the old stock. I used it today on a "New" short comb. Unbelievably sharp and smooth. I am just delighted with these and hope the new stock is just as good.
