Non-Parallel Grind?

While I'm waiting for my first shave-ready razor, I decided to buy a junk blade and practice taking off rust, removing scales, removing nicks, etc. Figured it'd be better to do all this for the first time on something I don't care about.

Anywho, the blade I bought was fun to play with, I used my friends whetstones to play with the edge and attempt to take nicks out and get a feel for what honing might be like (remember, I didn't care about doing this exactly properly, I just want to get used to the feel).

My question is, it looks like the thing has been ground way down so the blade is not parallel to the spine, the spine looks it, like somebody ground it themselves or honed it funny for a long time. I was wondering if there was an intentional reason someone would do this. Big chunk of blade missing?

I wanted a second opinion to my totally newbie eye:

By the way, here's a before, just for good measure:

Thats what we call a well worn razor. I'm not sure I would spend too much time with it unless you are collecting razors and its some rare bird that you need for collecting purposes. I'm not sure I would ever want to shave with that. Of course you could probably grind it down to a 2/8 or 3/8s and then you might have a useable razor. But personally I think I would use it as a letter opener.

That razor has been honed to death on a wide stone. It will probably shave if honed properly but don't ask me to hone it!:)

Use it to practice your honing stroke. It will be good to use when you check your hones for any embedded grit after you lap them.
