While I try not to slander manufacturer's, I really don't correct any issues with their product, but instead ask for a replacement.
If some of our tools were $10, sure. . .take the time to fix it. However, with LN and LV, we do pay a lot for tools that are meant to be close to perfect and both companies tout their attention to detail. Also, I like to make the manufacturer aware because it could be a systemic problem that has crept in, for instance a grinding head or holding jig that's become damaged in some unforeseen way.
That being said, I've only had issues with LV, mainly because I've primarily bought from them. Cap irons came a little wonky to how they sat on the blades.
