Viper teamed up with Jens Also to design the Orso, a high-performance knife for everyday use. With quality materials and a straightforward yet ergonomical shape, the Orso is a versatile and reliable tool. The blade on ball bearings is made from powder metallurgical, cryo-tempered M390 for outstanding edge retention and stability. The titanium-milled clip and spacers are true works of art. The knife has a Titanium handle and a satinized blade with a linerlock.
