Pullrich. It is a European style entrenching tool, and that form was used by many countries. I live in an area that when you dig into the ground, about half of what comes out of a hole is rocks and stones. I recently had to put in a new post for our mail box and went down to Home Depot and bought a Post Hole Digger. A complete fiasco, did not get a single bit of dirt out of the ground with that PHD, just too many rocks. I ended up with a small pick axe, a Finnish entrenching tool made by Bilnas (which I bought to go with my Bilnas Finnish woodsman axe) , which looks a lot like yours and finally a small folding head shovel, that looks like a US M1951 E tool, to dig the hole. Some years back I was going to do an article on E tools so went down into our woods and over a few days dug foxholes with each E tool. I would dig for 10 minutes, take a photo, 10 more minutes, a photo and ten more minutes (30 minutes total) and the final photos, and measure how deep the foxhole was. I tested a M1951 US E tool (head folds and has a pick) a Glock E tool, Cold Steel, and a Fiskars NATO E tool. The M1951 was at least 12 inches deeper at the end, then the second place finisher, which was the Fiskars, and the Glock and Cold Steel were way behind. The Glock came apart as I was swinging (where the handle extends) but I was able to get it back together (twice) but thought an infantry man digging in under fire would have lost it when his E tool came apart. The M1951's pick and shovel at right angles to the handle just could not be beat. Dig with the pick, rotate the handle and clean out with the shovel. The Fiskars, with the shovel head at right angle to the handle worked well, but not as well as the pick. John
