Thanks Chris, that is why I did this post. Most hobby grade tweezers can be pretty marginal. The tips are part launchers from the git-go. They can be made into decent tools with just a little work. Follow that link as it gives a step-by-step way to do it. The bad part is when a pair of tweezers requires too much pressure to close them. In that case it can become easy to damage or launch a part. Tweezers that take minimal pressure allow you to "feel" the part when it is picked up and helps to keep from squeezing too hard.
Bob I am not real sure what you are referring to, the MENG tweezers are hobby grade, but are more expensive than other tweezers that would probably work better. For folks that don't know any better they would probably work OK, but the slightly rounded edges and pick up surfaces that are not perfectly smooth with a slight grain could give folks problems.
No matterthe source, all tweezers will need some corrective rework to make them, or keep them really useable.
