Rather than have them spread all over the place, I thought it might be useful to have them collected in one thread.
This one recently released:
http://www.academia.edu/3572087/Sword_parts_a...al_society
| Quote: | | A key feature of swords from the Migration and Merovingian Period is that they consist of many different parts, as recently highlighted by the discovery of the Staffordshire hoard. This paper seeks to order sword parts and their depositional contexts, by interpreting them as symbols of kleptocracy and animated by their object biographies in the Migration and Merovingian Period martial society. |
The link to this one was lost in 'the great crash of ought thirteen'
http://www.academia.edu/2649664/A_group_of_Vi...f_the_time
| Quote: | | During the 1998 excavations on the Garrison site at Birka, Uppland, Sweden, a spectacular deposit was found in a post pit belonging to the Warrior’s House, one of the finds in which was a bronze sword chape of a type not previously found in Birka. The scarcity of this type of chape and its distribution pattern aroused a series of questions concerning its function, iconographic symbols and whether or not the pattern of distribution of a materialculture through diplomatic and political contacts can reflect a political landscape? An iconographic study, partly based on a surface structure analysis, is made of the newly found chape. |
and I just found this while looking for the last one:

I'll add more as they come to light, please do likewise.
Enjoy.

This survey actually includes pieces from modern day Czech Republic - specifically the Moravian region from the 11th - 13th centuries.  If memory serves, some of these pieces are on display in the Brno and Olomouc museums (the former really needs an overhaul, the latter is small but quite decent).

Some very interesting swords here! I really like some of those unusual pommels...

There are some great publications on swords coming out of Czech Republic in the last decade. I LOVE LOVE LOVE how they all include detailed metallurgical reports with construction methods. I totally geek out on sword metallurgy.

There is no point analysing the nickel content. Nickel is preferentially lost as meteorites oxidise, so the longer they have been on Earth, the less nickel they contain. There are surviving daggers that we know were made of meteoritic iron yet contain almost no nickel.
There are naturally-occurring nickel-iron alloys in several parts of the world - where basaltic magmas have intruded into carbonaceous sediments and these can be made into weapons (no smelting required) that are indistinguishable from Tut's dagger. There were also nickel-bearing iron ores in that part of the world during that time so any iron smelted from those ores would also contain nickel.
Apparently the best indicator of meteoritic iron is whether it contains cobalt, not nickel. Tut's dagger does contain cobalt so it could have been forged from meteoritic iron. An easier way is to simply see if it has any bloomery slag in it.

The department of Earth and Planetary sciences disagrees with you strongly on this, Dan. There's strong reason they did the nickel tests that make the article completely valid and rather fascinating. It's certainly worth the read.

As I already said, we have blades that we know were made from meteroritic iron that contain almost no nickel at all.

1. There's plenty of point in measuring the nickel content. It doesn't automatically give a yes/no result for whether the iron is meteoric in origin, but there is still plenty of point in such analysis. In this case, the dagger is over 10% nickel, which by itself is enough to say it's almost certainly of meteoric origin. As a rule of thumb, above 8% means meteoric.
2. The cobalt content was measured as well, since the cobalt:nickel ratio is important when trying to identify whether iron is of meteoric origin. Without knowing the nickel content, the cobalt content is of little use - it's the cobalt:nickel ratio that's most useful.
3. Naturally-occurring telluric nickel-iron alloys are distinguishable from Tutankhamun's dagger, just on the basis of their nickel content (typically under 4%). More generally, it can be difficult to identify iron as telluric native iron rather than meteoric in origin, since as well as some meteorites having similarly low nickel content, telluric iron can show Widmanstätten patterns (a Widmanstätten pattern does identify iron as non-smelted, but doesn't distinguish between telluric and meteoric). I haven't seen the range of cobalt:nickel ratios for high-nickel telluric iron (Jambon only compares high-nickel smelted alloys), but perhaps these would help distinguish between such telluric alloys and low-nickel meteoric iron.
4. It's very common for pop science web articles to not give the full details. It's often useful to read the actual scientific paper describing the work before dismissing the results. Sometimes even to find out what the results are, since the pop article doesn't always get it right.
Jambon doesn't analyse the dagger; he uses the measurements by Comelli et al. 2016, (10.8% Ni, 0.58% Co, and also quotes the measurement given by Ströbele et al. 2016 (ref below), 12.9% Ni.
