Help Id'ing some tools.

Hey gang,ive had these forever and just curious what were used for?

 

Pretty sure the big black hand-grip thing on the top right is to set teeth on a handsaw after sharpening with a triangular hand file. Teeth on a handsaw are allways at a angle to the blade. This tool bends the teeth out. First one side, then turn the handsaw around for the other side.

 

The tool with 2 wing nuts is used to pinch a hose shut .
