Recently I`ve been looking at Ontario Rat-7 and the RTAK the Rat-7 comes in either 1095 or D2 and the RTAK only 1095.

As far as steel goes how do those rate for durability? The knife is large and if used regularly to chop, clear, cut will it hold and edge and NOT break/crack/shatter ?

What are GOOD steels to have in knives?

I`ve found http://www.admiralsteel.com/products/blades.html but it doesn't specify qualities of each type?

Thanks!
