The Craftsman Weedeater model 316.790100 was manufactured by Husqvarna. Craftsman, a brand known for its outdoor power equipment, has partnered with various manufacturers over the years, and Husqvarna is one of the key producers of their outdoor tools. This model is part of their line of trimmers and string trimmers designed for residential use.
I was told by a Sears employee, who works in the outdoor power equipment section, that all Craftsman yard tools are manufactured by someone else. The Craftsman logo is just a brand that is placed on another companie's tool in hopes of increasing sales. He told me that Craftsman string trimmers are made by Husqvarna.

Oh, dude, Craftsman leaf blowers are made by the company Craftsman. It's like their whole deal, you know? They're like, "Hey, let's make leaf blowers," and then they make them. It's not rocket science, man.
Some are, some aren't. A lot of Husqvarna products are sold as badge engineered items, as well (Craftsman, American Yard Products, Yard Pro, WeedEater, McCulloch, etc.).

Sears sells them but they are made by various manufacturers under the craftsman name, depending on the year and model.
