I use the G.I. Memorandum books for work purposes. Mostly because I archive these books and like the bound nature of the pages. They have a great durable soft cover already and are hard to beat right out of the box, but I did want a metal cover. I just happened to see these at a reasonable price point so I pulled on it. The others I have seen were nicer, stainless, titanium, etc., but really pricey for me.
