I really like Karl Lagerfeld e/d/t because it is definitely a manly scent. Although I have not tried the a/s, I would assume it is a toned down version of the e/d/t.

I found this Product Description:
warm spices and tobacco blend with musk and amber, a very masculine scent.

Also, this is the best price I have seen: Amazon.com: Lagerfeld by Karl Lagerfeld fro Men 4.2 OZ Classic After Shave Unboxed: Health & Personal Care
