Actual medieval bookbinding tools are almost nonexistent. Apart from a few finishing tools, there really aren’t many documented, extant examples. That’s why a knife that John Nove brought to my attention is extraordinary. Could it really be a medieval bookbinder’s knife? A note associated with this knife claimed it might be.
At first glance it looks similar to a typical “gift set” carving knife given to newlyweds in the 20th century. The tip looks to be slightly serrated, or perhaps just extremely pitted. The handle has the tonality of antler, but it is actually a carved, lightweight wood according to John. This strikes me as odd: historically, the handles of most knives tend to be a dense exotic woods, bone, horn, or antler. The blade is extremely rusted, while the handle is relatively intact. Is this a red flag?
Is it a knife that maybe belonged to a bookbinder or bibliophile, hence the very cool handle decoration? Or is it an assemblage of some older and newer parts? Or something else?
The handle is what makes this knife so special. These intricately carved books are convincingly realistic. To me, the books look Gothic, and possibly Germanic, given the overall morphology. The sewing supports appear to be double cords or split tawed thongs, both appropriate to a Medieval book. The pronounced endbands, with the cores lying on the spine are also consistent with this. The clasps look like split thongs, possibly there is a pin attachment? The very rounded spine with pronounced supports extending onto the face of the board is typically Gothic. The carved representation of panels is also typical, though a little odd with the carved triangles, though this might be a limitation of the size of the original and the carver. After all, it only about an inch wide.
The curved, almost spiral grip in the center of the handle is similar to Medieval carved columns I have seen in the Cloisters at the MET. The traces of red (paint ?) on the page edges is somewhat unusual, yellow or a blue would be more common, if in fact it is a German binding represented. The overall length of the knife is 9 inches, with 5 inches for the blade. The blade is quite flexible, with the back measuring only .012 inch.
The elaborate handle seems out of place with a functional tool used by a craftsman, but there are many examples of very elaborate Medieval tools with zoomorphic designs carved into them. The ferrule is also strange with its scalloped collar. John Nove wondered if the blade might have been stuck into an older handle. Book-themed ornamentation on a knife like this might indicate a 19th c. page opening knife? The size is right for that as well.
If this is a medieval bookbinder’s knife in the German tradition, are there modern styles we can compare it to? And how would it have been used? I’d guess that all knives were originally undifferentiated for different trades. Knife-makers would make their knives for a variety of purposes. When did the specific needs for specific trades start? Even today, shoemakers and bookbinders, in the English tradition, use a the same Barnsley paring knife, older examples having an image of a shoe stamped on them.
I’ve noticed the similarities between German style chef’s and bookbinder’s knifes for a while. The primary one is the taper of the blade from the back to the cutting edge, parallel to the length of the knife. It doesn’t make sense functionally to make a paring knife like this, so German binders wrap the handle with leather, cord or thread to hold it more comfortably. The thin metal around the cutting edge is quick to resharpen, though. There are also the three cutlery rivets on the handles; these are technically called scales on a full tang knife.
The text mentions that the Offenbacher shape is good for weaker leathers, and the Parisian shape is good for thicker leathers. For the leather to be held in the hand position depicted with the Parisian knife, the leather would have to be very thick, almost more of a tanned cowhide, rather than a typical bookbinding calf, sheep, or goat.
The paring knife in Zaehnsdorf’s manual has a similar shape to the medieval knife and moddern chef’s knifes, as do the ones in Peter’s 1928 Braunwarth & Luthke catalog, below. Most seem to have a taper towards the edge of the blade on the left, as indicated by the thicker black line indicating the back of the blade.
To return to the central question. Is this knife a medieval bookbinder’s knife? Without having any scientific analysis of the materials (XRF? FCIR? Carbon dating on the handle?), or more information on province, and examining it in person, I can’t say for sure.
But I can say it is an intriguing object, worthy of further research, preservation, and hopefully clarification in the future.
