Here is my attempt to a "translation" I once fabricated for m4220 of an article on Lippert's Waidblatt and the reproduction by master knifemaker Ulrich, :

(Both Lippert's and Scholz' Waidblatt designs are almost forgotten, Frevert's design now the only one known to most hunters. Some time ago I met a hunter and knifemaker who showed me his idea of "the ideal hunting knife". He was not aware of the fact that he had merely reinvented Scholz' Waidblatt, he had never heard the name before. Though Lippert's Waidblatt is forgotten too, I will try to beat the machine in translating. One of the more serious errors the machine made: the verb "abfangen", by word origin "to catch off", common dictionary use "to intercept" like as in "Abfangjaeger" = "interceptor fighter", but in hunter's use "to apply the coup de grace with cold steel")

He (W.Ulrich) was featured in Time magazine August 20/27 2001 “Why Europe's craftsmen are still the best” with a story on him named “The working German cutler Willi Ulrich”:
This special hunting knife was designed by by renowned artist & hunter F. K. Lippert ,who registered the patent application in 1936 for the Lippert's Waidblatt. In 2001 Willi Ulrich decided to revive this hunting equipment of knives & tools with a special production of 200 Replica’s as only about 12 originals marked with Scherpings name were sold from his shop. Only a handful of originals have been seen. These reproductions were executed in precise detail, each presentation box set is uniquely numbered and contains the “Lippertsche Waidblatt”, a smaller skinning knife and a bone marrow awl/sharpening steel, all contained in a fitted leather sheath. We have been able to obtain the advertisement from “Wild und Hund” hunting magazine 1937 as well as the artists concept drawing & the patent application provided with the Ulrich set. Another article penned by author Richard Schmeider titled “The Lippertsche Waidblatt, Rare and sought after”. The Waidblatt designed by Oberforstmeister Walter Frevert is the classic among cold steel hunting weapons. Few people know Friedrich Karl Lippert's however, but it had real benefits in practical use for hunting.
“In October 1936 the painter and hunter Friedrich Karl Lippert submitted to the Patent Office in Berlin a very special Waidblatt, which is meant to be superior to the usual Frevert's Waidblatt for applying the coup de grace to wild boar as it was better suited to easily penetrate the tough skin. With the double curvature of the sharpened back of the blade point Lippert wanted to ensure that the blade not only penetrates into the body but also the cutting of blood vessels on withdrawal and thus effecting a greater blood loss . Furthermore Lippert's Waidblatt was designed by an artist who designed the handguard shaped like a wolf hook, a mediaval trapping tool and heraldic symbol of Hanoverian hunters and foresters. (Unfortunately the artist gone wild put the handguard on wrong way.AE) The blade had a length of 230 millimeters, 38 mm wide at the handle and from 42 to 44 mm wide near the point. The blade back was 5 mm thick at the rear, at it's center, on the other hand, it was a massive 6.5 mm thick.
Enthusiastic supporters: Forstmeister Friess, a known hunting scribe too. Lippert's blade was sharpened at the back up to almost half of it's length so that the blade for the coup de grace on wild game is optimized. Superior master forester Rudolf Friess used such a Lippert's Waidblatt on his boar hunts in the Spessart forests and was excited. Friess was mistaken, however, when he saw it as a reproduction of the Old-Hanoverian "Couteaux de Chasse" The latter was merely a short "Hirschfänger", hanger in English, with a stout straight blade. As it was handmade to order. Lippert's design, however, never reached the popularity level of Frevert's Waidblatt. The rare specimens that were available through the Heinrich Scherping gunmaker in Hannover, only available made to order as an exclusive custom job are now difficult to find and most sought after collector's items”
More from the Ulrich documentation:
Why is Lippert's Waidblatt going to be reproduced?
The precision of a rifled barrel is unique.
Following this the sophisticated steel blade with a blade length of approximately 23-25 cm, has a width of 5 cm, the back thickness is 5mm, it is double edged with a rounded point to prevent to catch on ribs and hard tissue, to penetrate into soft organs (heart/lungs) The heart does not need to be penetrated, as death is caused by air in the ribcage cavity, causing the lungs to collapse, resulting in imminent and painless death.
These are quotations from the book of F. Karl Lippert which appeared in 1954
“Vom Schuss an” = After the Shot, Osterwald Verlag Hannover/Germany
The pro and contra of the coup de grace with the Waidblatt was for the maker of “Lippert's Waidblatt” not arguable.
Some comments from a contemporary hunter
As this kind of killing a wounded animal has many supporters, the “Lippert's Waidblatt” is even today still actual. The coup de grace by shooting is often impossible, therefore fast cold steel is a necessity. For this use the Lippertsche Waidblatt , developed by F.K. Lippert, is unequalled by causing air embolism instantly, even through thick Boar skin, as recommended by well known Forestry Commissioneer Rudolf Fries in the 50s, who’s experience in the past was gathered by numerous Boar hunts.
With the present increase of wild Boar hunting, the “Lippertsche Waidblatt” is the best cold steel weapon. (October 2001 by Richard Schneider)
