I'm a big fan of Astra SP blades. I rarely use anything else. This morning, I was surprised when my fingertip caught on a very sharp corner on the tab at the end of one of the blades. I've included an image to show what I found. The right end (2) is normal. Both corners of the tab on the left (1) are very sharp. The lower one is more like a tiny hook. Since all of my razors leave the blade ends exposed, I decided not to shave with this blade. I use about 100 SPs a year, and have never noticed this before. But just in case it might affect others, I thought I'd post a "heads up." FWIW, this blade came from a 100-pack purchased from Amazon in April 2015.
