Get the aluminum one if you want a M16. The plastic ones use not so nice AUS4 steel
I was under the impression it was AUS-6M. Still nothing to crow about -- comparable to 440A.
I think the M16-13Z (which I believe is the Zytel handle version) is a great knife design. It's very rugged and is a nice size for pocket carry. The handle really fills the hand, and the LAWKS safety mechanism gives you fantastic confidence in the lock strength. It also has nice thick liners and I was unable to get mine to fail with spine whacks with the safety disengaged. Also, with the Carson Flipper, after a little practice it deploys as easily as a full auto/switchblade.
If you get the aluminum handled version it will come with AUS 8 steel which is a little better. However, it will be heavier as well.
In short I think it's a great knife, especially for $30 which is the price at Walmart. I do wish the Zytel version came with a little better blade steel but what can you do. I think it would make an extremely suitable self defense knife due to the strong construction, reliable lock and rapid deployability. If you're going to use it as a work knife I'd probably go for the aluminum handle version with the better blade steel.
I'd probably compare it to a Kershaw Leek (another great knife design) in terms of great ergos, deployabilty, and blade steel quality. The leek uses 440A, is a liner lock, and uses a flipper mechanism to open the blade. Differences are, the M16-13Z is a little bigger, and the blade is not spring assisted like the Leek. So, while the Leek is a LITTLE easier to open, the M16 I believe would be legal in more jurisdications because it doesn't have a spring loaded blade launching system and therefore can't be classified a switchblade. The M16-13Z is also cheaper than the Leek, and has a much stronger and more reliable lock especially with the safety engaged. My Kershaw Scallion (same lock as the Leek) will fail with moderate spine whacks.
