Q: I have the solid stainless model of this but it became dull seemingly overnight. I ordered this one to replace the original pair and could not be happier. Once again I have the precision of the original, plucking ultra fine hairs with aplomb, and multiple hairs per squeeze. I was able to file my originals and get them back into a usable condition again. However, they will be relegated to back-up duty at this point since the new ones work so perfectly. In case you're wondering, this new black pair measures 3.75 inches in length.
A:
positive
