I use Schick ST2 slim twin available in packs of 12 at the local super market, CVS, Walgreen's. I believe around $10.00 per pack. Current coupon special two packs for $.99ea. I am Italian with very course curly beard and the tendency for ingrown hairs. Also plenty of Italian nooks an cranny's and edges to steer around. The ST2 is a double edge blade with very slim maneuverable head. I shave in the shower daily so the steam softens my whiskers. I get about a week out of each razor. rarely a nick, ingrown hair or rash that isn't caused by me rushing or using an old razor. I also used regular soap as a lubricant until it started drying out my skin. I now use a gel such as edge or similar with a moisturizer. I can get down into the cleft on my chin and close by my nose and lip with out issue.
I keep two or three new in my dopp kit.
