The practical reason of a frog is the ability to wear a sword. Is your main question "what may be the practical reason for not wearing a scabbard"?

@Alexander Partially. I suppose you could either read it as “why would you wear a sword frog instead of a scabbard?” or “why would you wear a sword frog as well as a scabbard?”. Both of these would be perfectly valid interpretations of the question. Essentially i’m looking for any uses of this for a fantasy adventurer who has a real, sharp weapon, rather than a replica one.

I might have been wrong with my use of sheath vs scabbard. Let me rephrase. You can think of a scabbard as consisting of two parts - a frog and a casing. Only the leather parts do not connect directly to casing but form a slot in which the case is held.

You use a sword frog because swords are heavy to carry around all the time, and why not have your pet frog hopping along next to you and carrying it? (Your pet frog is apparently at least as large as a golden retriever.)

@sphennings Can you elaborate? I could easily put a sharp sword into a frog just as well as a sheath or scabbard. They aren’t designed for that (as i mentioned, you’d be more likely to cut yourself) but i could easily carry a sword in a sword frog.

But by that logic you could just stuff the sharp blade in your pants pocket. Frogs were never designed to carry sharp blades. Scabbards, on the other hand are designed to carry sharp blades.

Frogs were designed to hold a scabbard, they are part of the scabbard. They were how to attached the scabbard to your person. frog is a term for a Y shaped piece of leather used to join two things. The frog allowed the sword to sit at a comfortable angle, easy to draw but not always in the way.

This question could be improved with a little research, this should have been asked on the history stack not here.

@John Perhaps, but a question being eligible to be asked on one stack does not automatically mean it is ineligible for another. Also, I did research my question before asking it here “as far as i can tell” and “ As there are no archeological findings of sword frogs from the medieval period that I know of” should imply that i have researched it. Perhaps i was looking in the wrong places, but I can’t show an absence of evidence in any other way than by saying “i couldnt find anything”

What I meant is should have asked about it on the history stack first as they could have a easily shown you examples and told you what frogs are for. there is a lot of things we have little artifact evidence for because they are made of things that rot. If you are having trouble researching something, try asking the stack devoted to that field of research.

Was coming to this question to see the practicality of frog-shaped swords

When I saw this question in the Hot Network Questions list I had a vision of adventurers employing enchanted frog-armorers to manufacture, carry, and care for their swords. After that the question was, frankly, a bit of a let-down... :-)

Why do you want someone to use a sword frog without a casing? These sorts of questions should always include that because it generally helps with answering the question.

@BobJarvis-ReinstateMonica I was let down too, because I thought it was something like this (a character from the JRPG video game Chrono Trigger)

The reason why sword frogs are used in LARP without scabbards is: a) a LARP sword isn't sharp, hence there is no need for a scabbard; and b) a LARP sword already has the shape and dimension comparable to a scabbard. Thus, for LARPers, it's very obvious to use the frog to carry the sword; as opposed to historical people, who used frogs to carry the scabbard which contained the sword.

I keep reading "Why would an adventurer use a frog sword?" which opens a whole scala of new questions...

@Martijn - frog swords must be adapted to the requirements of an amphibious wielder. Sharp? - obviously. Low air/water resistance? - of course. Neutrally buoyant? - absolutely! What good is a sword that sinks like a chunk of steel in water? Clearly there's a lot of metallurgical work to be done in terms of developing steel alloys which achieve something close to neutral buoyancy in water!
