Shredders under the Kobra brand, with its distinctive snake logo, are produced by a company called Elcoman, based in Italy.
Kobra shredders' blades turn at a high rate which, according to the company, combines with turbine airflow to shred faster. The company is also proud of the physical appearance of its shredders: "smooth and elegant."
The Kobra Cyclone can shred 500 sheets of paper at one time, on some models all the way up to security level 5 ("top secret or classified"), based on which adaptor the customer chooses. (Security levels can be upgraded later by switching out a part.) The Cyclone machine also features a rear window through which shredding and paper level can be observed. It also shreds cardboard, floppy disks, CDs, aluminum cans, and plastic bottles. A step up from the Cyclone is Kobra's High Security Shredder, which offers greater capacity, quicker shredding, quieter operation, and, with a shred size of 0.8mm x 5mm, claims to meet security level 6, "top secret or classified" under DIN (German Institute for Standardization) standards and is compliant with U.S. Department of Defense and National Security Agency requirements for government documents. In fact, Kobra shredders are presented to presidents and their delegations during the G8 ("Group of Eight") leaders' summit, and the company is a main supplier to the FBI, CIA, and NSA.
Other Kobra models, features, and functions include touch screens, low-emissions Energy Smart power-saving mode, automatic oiling system, and a metal detection system. One model, the Kobra Compactor C-500, compresses the shredded material as well.
In the United States, Kobra shredders (strip cut, cross-cut and micro-cut models) can be purchased through various dealers. The most powerful and secure can cost more than $30,000.
