Andrew, your blade appears to be of some interest, but unfortunately has apparently been sanded (sandpaper and other hard grit abrasives favored in the West "smear" the metal surface and leave a mirror-like finish, masking much of the activity in Japanese blades). The (very) good news is that whoever sanded the blade didn't round off the shinogi (had this been done, a massive amount of metal would need be removed to bring them back to proper sharpness).
In order to bring out your blade's activity, I recommend you get some good uchiko powder or uchiko ball and devote a few hours uchikoing your piece. There are different styles of doing this, and I don't want to start a flame war over how best to go about it. A search here on "uchiko" will likely surface some various opinions. It will seem slow going at first, but after a number of hours, the hamon and other hararaki will come out (the pitting won't, this requires a foundation polish by a professional). Just be sure to uchiko only from the shinogi to the ha, not the shinogi ji, and don't ride over the shinogi itself, again to avoid rounding it. You can do this while, say, watching TV or listening to tunes, just don't get too complacent and slip, you can slice yourself badly if you do. You'll soon get a feel for how many swipes one dusting will last (some people say only to go once, but this isn't appropriate for the "power-uchiko" job I'm recommending here), also, if you do slip and put a fingerprint on the metal (hopefully no blood), you will see how many swipes are necessary to get all the skin oil out of the metal (more than you might think).
Good luck with your first Nihonto, and please post some more pics after the activity comes to light!
