Is this normal/acceptable (pls see pics)

They're called needle files here. I see knives like this quite regularly. I've even had knives with blades that are practically at a 45 degree angle! Flaw or not, it's something I personally detest.
 
Google EZE Lap Diamond Needle File Set. There are two sets. 607F (fine) and 607C (coarse). They look like the ones pictured above.
 
Hi Sarah! Thanks for the pics. Good to know I'm not the only one bugged by this "characteristic". Looks like I might just have to break out the small files and have a go at it. Mine is after all a not-very-expensive user knife so I'm not afraid of marring it. And I do love to tinker so this might be an ideal project.

Seems like this was suggested to you in the 2nd post.

Looks like the back spring or the notch on the tang is too long. File the spine of the blade where it contacts the back spring and that should take care of it.
 
A 'credit card' diamond hone also works well, for filing the tang face. It's very thin and the edge of the hone can be used in tight quarters. I used mine (DMT Fine) to straighten out the lines of an underbladed Peanut (or at least 'crooked', if the terminology doesn't apply ;)), on the clip blade. Might see the end of the spring 'drop' a bit after the adjustment (it might settle below flush with the liners, when the blade is open), but I view it as an acceptable trade-off.

As I said above, I get the OP's point and Mike's point but once the material is removed from the tang in order to make the blade spine parallel with the spring, it will still be underbladed, at least in the case of the OP's knife and most others where the blade starts out not being parallel with the spring.

I'm OK with underblading after the modifications to that knife. In my opinion it's still better than a blade that's not aligned with the backspring. And the underblading is very slight - maybe 0.5mm, if that. Acceptable in my book.

After my initial success, I did the same mod to another knife I had and this time, there was no underblading.
At least now I know what underblading is. Always learning something new from the helpful people in this forum.

Yes, good on you for fixing it yourself, as Sarah pointed out, you do need to slow with that process and also I'd recommend applying some oil or taping up so the filings don't get down into the workings of the knife.

I did a thread on this a while back about my Case Peanut I was lead to understand that the Case Peanut was designed to have this blade angle, but, I couldn't live with that and rectified it as best I could ;)
