I got these as I do pits and pieces or family hair, including my own, and needed new scissors after hubby's failed sharpening attempt.
Somewhat better quality that I expected at the price, and have no doubt that they will last some years (if I don't let hubby near them!).
They have brillian little tightening screws, so you can tighten or loosen by hand and don't need to run round looking for a screw-driver.
Also, they are ALL METAL, as suggested by the photograph, and do not have plasic handles as stated in another review - I think perhaps they received the wrong item!
In summary: cheap, cheerful, functional and a snip at the price (sorry - couldn't resist it!)
