What is this???

I can't help you on the translation of that German word(s). Someone in the Amish community might be able to translate German. Their original native language was German. I believe some of the more traditional Amish still speak a dialect of German? The German word(s) on the case may only be the name of the maker of the case and not of the lancet itself???

The following page has about every kind of fleam, lancet, that I care to know about. Several types of spring lancets are pictured. You might scan through the pages via the index on the left to see if any matches this one.

Several of the pages show the interior workings of the spring loaded ones such as the following pages.

A few minutes ago as I was bookmarking a couple of the websites with antique medical tools used in this thread, I stumbled on the German word printed on the top of this case. I believe the word is
"Traŭnichtesbeißt" that translates "Do not trust it bites." I found it on the case of an Austrian spring lancet.

I then looked around for Austrian lancets. I found a later bloodletting instrument called a multi blade scarificator marked "F.D. Wien." Wien is Vienna. I believe to the right of the F.D. on this lancet was the word Wien. The site had no answer for F.D.
Scroll 1/2 way down the page:

WOW!!! That is one cool instrument!!!! The complete one that Susan first listed, if you noticed, they are ASKING $229. for!! No clue otherwise, but you're not going to sell it anyway!!!

 

Yes, they do speak a dialect of old German and even listen to it in their church services. Their Bible I in German. I'll pass all this information on to them tomorrow. Ladybranch, it looks just like the one in the first link you sent.
