Pocket knife with thumb hole: a classic among opening mechanisms
A pocket knife with thumb hole is one of the most recognisable, popular and practical variants. The round hole in the blade makes opening with your thumb natural and effortless. You don't need an extra button, flipper or auxiliary mechanism, just a smooth movement. This system is intuitive, reliable and fast, even allowing you to operate the knife blindly. Well-known brands like Spyderco have elevated the thumbhole to icon status, thanks to clever designs and thoughtful details. A pocket knife with thumb hole stands for simplicity, efficiency and timeless style.
