I've become interested in tweezers due to starting to play with watches. Whilst you can pay a lot of money for tweezers, it seems like it is more important to 'dress' them. That is to use files / stones to tune the ends of the tweezers to be appropriately sharp and have the right profile.
The test (I was told by someone in this forum) was if you could pick up a hair from a sheet of glass with the tweezer.,
The set I have cost under 20 quid for 4 and after filing and dressing (and practice) they are of that quality.
I don't think you need to spend a lot.
