Tool (band) intentions differently: "Tool is exactly what it sounds like: It's a big dick. It's a wrench. ... we are ... your tool; use us as a catalyst in your process of finding out whatever it is you need to find out, or whatever it is you're trying to achieve." After almost two years of practicing and performing locally in the Los Angeles area, the band was approached by record companies, and eventually signed a record deal with Zoo Entertainment. In March 1992, Zoo released the band's first effort, "Opiate". Described by the band as "slam and bang" heavy music and
Tool steel to the water-hardening class. These alloys increase the steels' hardenability, and thus require a less severe quenching process and as a result are less likely to crack. They have high surface hardness and are often used to make knife blades. The machinability of the oil hardening grades is high but for the high carbon-chromium types is low. This series includes an O1 type, an O2 type, an O6 type and an O7 type. All steels in this group are typically hardened at 800°C, oil quenched, then tempered at <200°C. The first air-hardening-grade tool steel was mushet steel, which was known
