Mine has a gap like yours, but about half as bad. The spring also rides a bit high like yours, but again not nearly as bad. I had to look pretty good to see that the spring was high. Mine is symmetrical from the end, not sure what happened to yours there. I don't really have advise for you on what you should do. If it were mine I'd use it, but for what I use my sodbuster for those things wouldn't bother me. My sodbuster is used mostly for hard and dirty tasks, so I'm usually wearing gloves or my hands are so covered in filth that I wouldn't notice the differences during use anyways. You might have different plans for your soddie, so your circumstances may be very different. If I got a trapper or stockman that looked like that I'd be sending it back.
I do have a problem with the viewpoint that a knife at that price point shouldn't be expected to be better. Rough Rider can do better with a multi-blade knife at half that price. Furthermore, Case isn't marketing themselves as a working man's knife. When I go to their website I see:
"Every knife is hand crafted by the most skilled artisans and cutlers in the business."
"Case knives are cherished possessions passed down through generations"
"Case knives are the most collected knives in the world."
"Case is dedicated to making the everyday tool into a valuable treasure for discerning men and women who want more than just a knife."
"With over a century of experience, we know how to make a premium pocketknife."
Nowhere do they say "We provide knives at different levels of quality to fit your budget." or "We make knives that are functional, and sometimes they look good too." I'd use your knife, and be happy doing so. However, I wouldn't consider it a valuable treasure for discerning men and women or a premium pocketknife. I understand that there's going to be products that slip through the cracks in any field, but looking over the Case display at the hardware store yesterday it was clear to me that they're putting out anything so long as it doesn't affect function. There is a big disconnect between their marketing and their quality control. If a company claims to employ the most skilled artisans, it's not unreasonable to expect a consistent quality in their product. I love my yellow CV Sodbuster Jr., but I consider that more a matter of luck than an indication of the quality I can expect from any other Case I happen upon.
These are just my opinions. I don't mean to offend anybody. I know that there are Case fans here, and I'm sure that you've had great experiences with Case knives. I have too. I'm merely sharing my opinion because the OP is asking for our opinions. My opinion is that if you're looking for a consistently quality knife you're better off going with another manufacturer. Case has premium marketing, but mediocre quality control. You might get lucky and get a near perfect specimen, but you're just as likely to get a knife that leaves you feeling unsatisfied.
