I quickly scanned the responses and didn't see another good point about this, thats the cost. If you plan on selling these, the 2 steels aren't aren't the best to compare to each other, the CPM D2 is pretty pricey, while the W2 from Aldo isn't nearly as expensive as any if the CPM steels, if the intended purpose of these knives are beaters, both steel as are good. I would have to facto rin the costs of both, and the prod/cons of each. Check out how much you can get CPM D-2 versus the cost of W2, I think you wil be surprised at the difference. If your going to be selling them, you will either have to price your knives so high no one wil be interested, or make them presents for family and friends. Do keep this in mnd, the main reason most people use W-2 is because it has th eability to produce a WICKED SICK Hamon! And it's holds an edge beautifuly! Sharp as it gets, HT'ing W2 is easy enough to do at home provided you have a kiln, personally I wouldn't do it without one, of course I could take the time to figure out how to get it right in my forge, it is possible, if your forge has an even heat. Since you send yours off anyway, it isn't an issue. BUT, I go right back to costs, most of the HT companies out there will charge more for additional services.
Thought I'd add some other aspects to choosing your steel. I'll also advise you to chck out Aldo Bruno's web site, I think its called, "The New Jersey Steel Baron", if you Google that you should find him. The main reason I recommend him is because he is, I think, the only steel supplier that caters to knife makers, if there is another I don't know who they are. He will sell a single bar or as many as you want. I support him not only because he specifically supports us, he's a great guy too!! Hope this helps in your decision, Rex
