It's called a Harp Tool because it's silhouette is evocative of the musical instrument. The byrd Harp has eight functional tools which rotate out individually from an outer ring and snap open, ready for use. Included: a slotted-head and Phillips-head screwdriver, punch/awl, gimlet, saw, corkscrew, file and small/large-head hammer that doubles as a bottle opener. When folded flat the Harp slips into a leather carrying case. It's like having a micro toolbox for your kitchen, car, boat, backpack or bike.
