i was just wondering i always hear about the problems with pattern-welded steel and damascus steel breaking do to low carbon content. does anyne have any pics of this issue or is this just a theory

Only "damascus" or pattern-welded swords I've seen broken are a few old Hanwei Godfreds, and that wasn't so much carbon content but poor grain growth or structure. It was just too coarse and pretty much just ripped apart. Hotspur had photos of his somewhere.

Broken Godfred- www.myarmoury.com/talk/viewtopic.php?t=14873&highlight=hanwei+godfred You should have no problems with PROPERLY DONE pattern welded steel. If you have doubts, stick to a reputable smith, or contact and communicate with the smith to get an idea of his knowledge level and procedures. Purchasing from reliable vendors will also give you a path of recourse if you should experience a failure with a mass produced weapon.

Battle ready means exactly that in my eyes, you can go to war with it. Wall hanger is a non functional sword like object.
Hanwei has had some issues, but they seem to work hard to rectify them. I just bought a Godfred this week and am not worried about it at all. Then again I am not going to chop cinder blocks with it, so it is all in expectations I suppose.
Pattern welded steel must be executed properly to be reliable. The preperation of the material, heat control, normalization and tempering are all more critical than a piece of mono steel.
Tempering would not rectify the ill effects of forging at too high of a temperature.

The welding has to be done at such a high temperature that it leads to massive grain growth. That should be rectified by multiple normalisation cycles at a much lower austentitic temperature so as to create much smaller tighter grain structure. But to get that you need two things - time, which costs money, and an accurately controlled consistent heating, which takes either a very good forge + forger (consistent lighting etc), or a kiln / furnace which is temp controlled. Both of which you aren't likely to get from a cheap forge making uber cheap production pieces like Hanwei.
Sad thing is you are right that most of these pieces will just hang on the wall or be used for light cutting a couple of time, so they will be wall hangers, the problem ones are like an acceptable collateral damage. It's all controlled by the dollar / profitability.

That's not the problem.

The Godfred is, that's the one that's been breaking.
I don't know about any breakages on this Shaolin sword?
