I don't think you have a problem at all. Since you have already voided the warranty, take the CF scales off the side of the knife. What you want to do is gain access to the screw that holds the pin that the lock bar pivots on. You can't see it when the scales are on the knife. With the scales removed adjust the tension on the screw so the lock bar moves easily just using your thumb normally. Then put the knife back together and adjust the blade pivot how you like it. That should take care of it as long as there are no bent parts (liner, lock bar, etc.). You might want to use loc-tite on the screw threads. THREADS ONLY! Make sure none gets between the liners and lock bar or anywhere other than inside the pin the screw screws into. I believe this will work. If it doesn't and I couldn't return it to where you bought it then I'd send it to Spyderco so they can fix it. It may cost you but IMO I like the knife enough to get it fixed. If you hadn't disassembled it already you could send it to them for free but still, I think you can fix it yourself (which is always nice IMO). Be sure to put a drop of good oil on your knife while it is un-put-together. I like to do it then because it's easier to see that all areas are getting lubed. I take the opportunity to apply Tuf-Glide for corrosion control and Nano-Oil on pivot points.

I think your Chaparral will get easier also even if it doesn't feel perfect after you try to adjust your lock bar screw.
