Bell Telephone must have wanted its workers to have durable equipment, because these cutters are top-quality in every way.

This pair has seen a lot of use, but it's ready for years more work.

The box joint is in good shape, with only a little play.

The cutting surfaces are sharp and nick-free, and the stripper notches are in fine shape too.

The metal finish is quite good - it's darkened from age and has a little very faint pitting, but is still very presentable.

The stampings on the head are distinct and clear. There's also a stamping of unknown meaning on the inside of one of the handles - see pics.
