Let's Do Dagger Data!

 (or: in which a random question makes me wonder a few things, so I made a spreadsheet about it!)

I know, I keep saying that I'm going to post about certain things (more on prize fights, more on Fabris' second book) and believe me I have some incomplete posts sitting in the drafts folder, but I got hit with a thing so here we are.

Over on the Facebooks, Lissa posted a question about daggers and dagger length, and it set off a short side conversation in the comments about what were actually used historically. So I decided to take my recollections and go get some data and throw them all together.

It's kind of an aphorism that fencers in the SCA trend towards "longer is better" in terms of weapons. As a general rule, there's something to it: being able to get your point on someone before they can reach you is always good. On the other hand, there are some important points which can throw a wrench into this. For instance, a smaller person using a sufficiently long sword can run into leverage and movement issues with the blade. If a sword is too long, a canny opponent can potentially get past your point more easily. A longer sword can be harder to keep free from being found by your opponent. 

...and a longer dagger can be much, much harder to maneuver around your sword into sound guard positions. Folks with shorter arms are particularly prone to this.

Those are all functional combat concerns, though. On a more practical level, a sufficiently long dagger becomes increasingly useless as a generally useful knife as well as becoming more and more annoying to wear as a daily carry item. If the dagger was purpose-built to be used as a dueling weapon, a companion to a sword, that might be one thing. As a day-to-day item though, that's something else.

So where does that lead us? 

Well, it lead me to hitting up the Wallace Collection, and going through their collection of daggers. I skipped past weapons which weren't plausibly parrying daggers from the period I'm studying - call it the mid 1500's onward - and then I weeded out more modern composites as well. (There were a surprising amount of 1550s dagger blades mounted on 1800s small sword hilts!) The bulk of them are from Italy, Northern Europe, Germany, or Spain. When an item had a date range listed, I used a year in the middle of the range for mapping purposes, but made a note of the range on the spreadsheet.

Of the 61 examples, all but two had the full weapon length listed. There were 23 entries which didn't have the blade length specified. Despite that, there was some neat data that I grabbed! As a note, one foot is 30.48 centimeters. I've been doing a lot of eyeball conversions during this!

Here we've got a breakdown of the overall length of the daggers in question. There's a really clear clump in the middle, ranging from just short of 37cm up to a bit more than 43cm - that's about 14.6 inches to about 17.1 inches of overall weapon length. Many fencers I know use daggers whose blades alone are in the neighborhood of those sizes, yet here we have a number of parrying daggers whose full length sits nicely inside the blade length of SCA daggers.

Now let's take a look at the weapon lengths compared to when they're from. The bulk of them are clumped from 1600 through 1615 or thereabouts, which works pretty well for what we generally study and recreate with rapiers. The much later group - 1650 through 1675 - is interesting in that the bottom half of the weapon length drops right off, leaving us with generally longer weapons in that time. We have a good number of full sail guards from Spain in there (and it may be totally composed of them, but I'd need to dig around further), with blades which are solely made for combat, and not at all suitable for general knife use.

So I mean, in short? (Ha ha.) Shorter daggers, more minimal hilts seem to be the order of the day. 

Also, here's a link to the spreadsheet if you want to take a look at the items, the raw data, or anything else! Warning: it's a work in progress! For instance, I need to clean up the conventions for descriptions (which is to say, I need to create conventions for the descriptions). Going forward, I'm hoping to get data from other institutions for fun as well. I want to hit up the Royal Armouries site next, but their interface just isn't as convenient for grabbing this information so it may take longer.

Anyway, more ongoing projects that I can do when I'm bored and that aren't dependent on the weather are handy. I'll still get back to the London Masters prize fights real soon though, and of course more Fabris.
