Tony Lennartz has been an icon in outdoor, survival and bushcraft for decades. His wide range of experience is based on his years of professional activity as a soldier and policeman, as well as on his lifelong passion for life in the wilderness. During many longer stays in the USA and Canada a close connection with the culture of the Native Americans developed, whose techniques and methods he could learn there. The training courses of Tony Lennartz, which take place on a large area in the Eifel, have taught thousands of participants the foundations of survival in the wild for many years. Like no other, Tony Lennartz bundles the wilderness experience from decades and develops his strategies and techniques permanently. Thus his knife designs are the essence of his knowledge and a clear commitment to his philosophy of uncompromising functionality.
