The well-known Opinel Pocket knife in a modern implementation. The handle is made of plastic and at the back of the handle you find a whistle (110 decibels) that works under all circumstances. The plastic is moisture-resistant and can be used between -40ºC and 80ºC. The blade is made of stainless Sandvik 12C27 steel and half serrated. This can be very convenient when needing to cut a rope for example. The blade is also equipped with a harp key (of 2.5-5.9 mm). In short, also a very handy knife for water sports lovers.
