Query: Not-so-great Heavy Metal

These scissors are heavy, metal, and unbelievably dull. The workmanship that went into producing these scissors can best be described as mediocre. But it's the dullness of the blades that bothers me most. I've bought numerous pairs of scissors and shears through the years and these are the worst I've seen in a long time. If there was an attempt to sharpen these at the factory, it must have been fairly halfhearted one. I am disappointed. Maybe I'll like them better after I sharpen them.
