The Kaschiereisen as this tool is known in German is made to shape and consolidate the spine of a book in backing where it was used as an alternative (or augmentation) to the hammer offering a high degree of control. Jeff Peachey has written about these tools several times, also sharing his growing collection. Most recently, Ulrich Widman "reintroduces" the tool to German bookbinding audiences with an upcoming article for the Meister der Einbandkunst Rundbrief (2021).
In the German bookbinding literature the tool has several spellings, Cachiereisen/ Cachier-Eisen /Kaschiereisen/Kaschier-Eisen. The interchangeable "c" and "k" are very common in German, the "c" being connected to the French roots of a word, but also as an affectation from when French was considered superior. Cashier, comes from the French "cahier" meaning signature/quire, or in our context a tool for working/shaping/folding the signatures. Eisen = iron, the material the tool was often made of.
In its history, the Kaschiereisen was sometimes two tools, in French the grattoir had a toothy end that grabbed the folds and provided the friction to push the signatures over to form the shoulder. The frottoir was smooth and used to smooth the folds and finish the shaping of the spine and shoulder. It also served to scrape off excess adhesive and ensure that it penetrated into the space between signatures.

The use of the tools is described on pages 214-15.
The use of the tool is also described on page 35 of Schäfer's Handbuch der Buchbinderkunst (1845). Schäfer refers to it as a Kratzeisen (scratch iron), and Reiber (burnisher) made of iron, these being distinct tools like the grattoir and frottoir. He also and issues warnings about the improper use of the tool and the damage it can cause.
Paul Adam describes using a Cachiereisen to finish the backing work of the hammer. The shape at both ends is smooth and curved like a frottoir.

|It was made by Jeff Peachey, called a "backing tool",|
and featured in his first catalog (link to 2nd catalog).
I love using this one on smaller, more delicate books.
