Were knives distinguished from daggers during the Middle Ages? Would a person be carrying both an eating knife and a dagger or one or the other?

I'm sorry if this question is too general, but I can't really figure this out. I initially assumed knives were tools and daggers weapons, but then Wikipedia (not the most reliable source, I know) claims rondel daggers were used as utility tools. And in the Statute of Winchester "Knife" is listed as a weapon.

[James Moore]

Going by AVB Norman's books, daggers are considered such by having symmetrical hilts, while knives are asymmetric. Which is of course, not to say that a knive cannot be used in the context of combat, and plenty of bollock daggers, basilards, and rondels have asymmetry in the blades (ie, single-edged designs.)

That said, eating knives - or more accurately, civillian knives (since eating is just once use they'd be put to) I've seen are invariably smaller (most are a 10-12cm blade length, vs a dagger of 20-30cm), and almost all have thinner blades (2-3mm, vs 4+ for daggers.).

Wikipedia is completely wrong with regards to rondels being utility tools.

[Leo Todeschini]

Eating knives are single edged but often had a partially sharpened false edge too and were of course generally used for eating though could be turned to other tasks.

Single edged knives such as the majority of bollock daggers and bauernwehr could be used easily for general tasks as having a blunt back edge is a great help and so poorer daggers usually have single edged blades as then they can double up for general tasks too.

Purely fighting daggers and higher status pieces usually have double edged blades or even triple and these cannot readily be used for anything other than fighting and posing.

The two items were different for different purposes so people would generally carry both. Eating with a dagger was a social no-no.

If you're carrying a stout ballock dagger, with perhaps 10" of single-edged blade, that's not a very convenient utility tool for many fine jobs. A 10" single-edged blade is the size of many people's largest kitchen knife - try whittling a toothpick with one, or doing some other fine job. Heck, try eating a meal using it as your knife.

Where a single-edged blade like that could be very handy is quite solid tasks - if you want to chop up wood it's not bad, for example. But for a lot of fine work it's just far too large.

And that's before considering hilts. A small utility knife tends to have a very plain hilt, allowing many grips that give very fine control of the point. A rondel dagger prevents almost all of those grips, which compounds the issue of having a much longer blade than is ideal for small work (you can get these options back by gripping the blade instead of the handle, but that has some obvious downsides...).

A small eating/utility type knife (think a 3-4" paring knife, practically), is very useful for a wide range of small jobs, where a long dagger is just too large. A large sax would be just as impractical for those as well, of course. The small knife is also lightweight and incredibly easy to carry, and doesn't make you look like you're about to stab someone up when actually you just want to pry the stuck top off your dice box, or whatever.

As far as I can tell a dagger was originally a tiny sword - a double-edged knife with a hilt and pommel. If it didn't have these features then it wasn't a dagger.

[Luke Adams]

Well, for the Chinese (and probably most East Asian people), the character 刀 means knife, or a single edged blade, while the character 剣 means sword, or a double edged blade.

I might be oversimplifying this, but I'd say:
Short single edged = Knife
Short double edged = Dagger
Long-ish single edged = Saber
Long-ish double edged = Sword

Of course, you can argue that sabers are swords or that, historically, roundel daggers could be single or double edged, but I think this terminology works best so as not to confuse the average Joe.

They must eat large lunches in the Khyber Pass 21 inch blade on this Khyber Knife. I think it illustrates that we will call anything single edged , asymmetrically mounted a knife... until it become a sword.

It ain't the hardware... Nessmuk just didn't have big knife skills.

Where I'm from machetes are used for just about everything and it works the same way with messers which once occupied essentially the same niche. Occasionally it is helpful to have a smaller blade, in a modern context I use an Alox handled Swiss Army Knife but a by-knife is also good.

As far as distinguishing daggers from knives go, you can do fighting or utility tasks with either to varying degrees of success depending on how the weapon/tool is specifically configured and what the job is but as a general rule knives are more cut and daggers are more thrust. We have fechtbucher that differentiate between various kinds of knives and daggers, it's not a night and day thing but they were aware of differences.

David Cooper,
What would you call an adya katti, being 54 cm long all in all, and the name indicates that it is a war knife?,

[Adam M.M.]

Thanks for clearing this up for me.

A somewhat off-topic question, did the English laws that forbade commoners from carrying swords within towns/cities apply to daggers as well?

[Glen A Cleeton]

The etymology for dagger seems anything but clear.
