The Spyderco Bug is the smallest diameter of the renowned blacksmith Spyderco and thus the ideal candidate for a knife that you hang on your key ring and thus is always at hand. Due to its extremely small size and its almost non-existent weight it does not interfere further on a key chain. Nevertheless, it does have considerable practicality - it is to open packaging, cut cable ties and ropes, small repairs or removing screws. The blade is very sharp cut at the factory. The spring mechanism has a high resistance and holds the blade in place well. In everyday life of a city dweller, it can replace a full size Swiss Army Knife in many areas. For me, the bug is now daily companion and much more than just a nice gimmick.
