I’ve replaced all of my 5B-SA tweezers with these tweezers because they’re stronger. The tips are little bit thicker, but you can sharpen them up with a diamond sharpener. Also, I bend them when I open up a new pair, so that they can grab the chips easier. If you’re thinking about buying some curved micro tweezers, then look no further…these are the ones that you want. Don’t be afraid to bend them to your liking.
