I'm not a professional locksmith or handyman. I bought these shears for use around my home and expect them to live up to the demand. They did. I used them on a gutter repair project shortly after receiving them and they worked really well. They cut well and are easy to hold and manipulate. If you need a pair of scissors for occasional household use, you can easily handle them. They're well built and can be used for more than just casual home use, but I haven't tested them in that type of usage environment.
