I like to use the 'demolition grade' blades. They ll cut wood, metal, plaster, wire, or pretty much anything you d care to throw at them. They're made from decent carbon steel that will take and hold an edge rather well. When bought in packs of a dozen, they can be had for about a buck each.
Knife blades. A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. A blade may be made from a flaking stone, such as flint, metal (usually steel), ceramic, or other material. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes.
