I own a Lesche, and I lend it out to those who I invite to hunt with me that don't have a digger. The digging tool that I prefer is my old Parker hori hori knife, made in Japan, that is more than 30 years old. I don't like the big guard on the Lesche although the steel in it is far superior to most of the metal in modern detecting recovery hand diggers. I have learned to use my palm on the top of the handle of the Parker, and shake the blade as I press down in hard ground, and have not cut myself (yet) by not having the guard to protect my hand. Steel in the Parker is hard and tough.
The Nokta/Makro digger appears to be a knock off of Lesche design with some added length to the handle and some added serrations. Only time will tell if the steel is up to the Lesche standard for toughness. Does anyone know where the Nokta is made? Maybe Turkey.... maybe China.....
