I have been back and forth over buying the JTN, but have not purchased it yet. As far as the steel goes, N690CO, I've had a few knives that used this steel and currently have two in this steel, a Boker ArctosXL, and a Fox Deimos. I like this steel and have always thought it, in actual use, similar to 154CM, which is another favorite steel of mine. I have found that it takes a good razor sharp edge, holds it for a long time, and is easy to bring it back up, sorry that I cannot be more specific than that. I am not sure exactly why Boker calls it N690Bo, other than the obvious. Bottom line is that it is a fine steel, maybe not the latest super duper steel, but a very usuable steel that will work well for most people.
