Over successive years common sense and a small amount of research prevailed and prompted the fashion to change away from 'eating daggers' to knives. Re-enactors are an odd bunch - at any meeting of more than two of us, you'll hear the word "Authenticity" bandied about with great authority. This word refers to the historical accuracy of costume and equipment, with the desired aim of having one's kit as 'Authentic' as possible. Oddly, though, there is very little research done by re-enactors as a whole; what usually happens is that in every group there will be a couple of history nuts who enjoys digging through books and researching items, who will interpret what they've researched and create it, then the rest of the group will go "Oh, that's really cool!" and make some as well, without doing their own research into it or forming their own opinions or interpretations. Most re-enactors seem to be very happy to follow the fashion of the time without questioning whether the person who did the groundwork for it actually got it right, or did a thorough job - which explains the 'eating daggers' and leads me into the next stage of my current gripe...
One of the C12 groups I belonged to was adamant that knives should be 'seax-shaped' - see the picture - as they'd found some in an archaeological dig, and that the 'modern' shape

So... I dug around and found some blade shapes that I liked (from the York dig - see pic); leather sheaths were a little more difficult, as leather doesn't usually survive 800-odd years well but there are still some around; I'm guessing about the colours (and going

The blades are highly polished as they rust less that way, cut easier, and don't trap food particles - which leads me to another gripe (or two): why do modern re-enactment blacksmiths make knives with pitted, blackened blades (except for the sharpened part), when swords have blades that are polished (all over) to within an inch of their life? I gather it's because they look more Authentic... What a load of rubbish - an unpolished blade rusts easily, makes slicing through food difficult, and why would one sort of blade be polished and another not? And why do re-enactors let their knives go blunt? Granted,

"Oh, I'm a Lady so I'd get my servants to do that", I was informed by one young woman... I started to explain to her about Ladies running households and having to know how to do something yourself before you supervised others doing it (or how would you know if they were doing it right?) and her pretty li'l eyes glazed over and I gave up in disgust - she was happy to re-enact and fantasise about being a Lady and dress up and look pretty as long as someone else would tell her what to wear, what to use, what her persona name was, yada yada yada... She was representative of a number of re-enactors who, if they can't buy something (with a guarantee of it being 'period') or get it made for them, are not interested in having it. The concept of researching something and getting their hands dirty making it is totally out of the question - which begs the question: how, then, are they re-enacting? Putting on a costume and semi-assuming a fairytale persona once every couple of months doesn't quite seem to qualify...
