Petersen type M sword

Many Viking Age sword are richly decorated, which makes quality reconstruction very expensive. That is why I was asked by my colleagues to provide an overview of undecorated swords that would be more affordable to reconstruct. I chose Petersen’s type M for its simplicity and major representation among Scandinavian sword finds. Because this type is often overlooked these days, it certainly deserves our attention.


The type M (also known as R. 489) describes a sword variant standing between types F and Q. It is characterised by a simple hilt in the shape of the letter I. Sharply cut cross-guard and upper guard are usually straight and of similar height. From the front view, both the upper and cross-guard are of rectangle shape, with the cross-guard slightly bent in rare cases. The upper guard is of simple shape similar to cross-guard, and the tang is held in place by hammering it into a rivet shape; the upper guard is never ended by a pommel. Sides of the guards are usually straight, less often rounded. An important feature of type M swords is undecorated hilt. Blades are usually double-edged (single-edged variants make up to 15% of finds according to Petersen) and simple, although we also know of some Norse and Swedish blades made of patern welded steel (Androščuk 2014: 386–7; Petersen 1919: 118). Petersen notes that none of Norse blades carries an inscription, which according to our information is still actual. That said, there is a variant of ULFBERHT inscription on a blade from Eura, Finland (Kazakevičius 1996: 39). While the swords are of simple design, they are made of quality materials.

Type M swords are in general up to one meter long, usually between 80 and 90 cm. The longest sword that we know of is 95 cm long. An average width of Scandinavian blades is 5,5-6 cm, sometimes up to 6,5 cm. Measured swords of average length weigh 1100-1200 grams. The shortest piece we are aware of weighs 409 grams and is 47,7 cm long, with blade having 38,5 cm in length and 0,48 cm in thickness (Peirce 2002: 86). This sword, said to had been found in a boy’s grave, seems to be a miniaturised, yet fully functional version. In order to outline anatomy of this interesting type, we chose six relatively well-preserved swords that we will describe in more detail.

We should also pay an attention to organic remnants found on type M swords. In general, we could say that many swords show traces of wooden panelling of the grip and wooden scabbard. Let’s examine several specific examples. The sword find from grave 511 in Repton, England was stored in wooden scabbard, that was inlaid with sheep’s fleece and covered in leather (Biddle – Kjølbye-Biddle 1992: 49). The scabbard was held by a hanging system, of which only a single cast buckle survived. The handle was made of softwood, which was then wrapped with a cloth strip. The sword from Öndverðarnes, Iceland (Kt 47) had a wooden grip wrapped in thin, plaited cord, and a wooden scabbard covered in textile (Eldjárn 2000: 326). Traces of leather cover were found at the tip of the scabbard, with remnants of sword belt slider located 3 cm below the cross-guard. In another Icelandic grave from Sílastaðir (Kt 98) – was found a sword with grip of wooden panels that were retracted below the cross-guard and wrapped with a cord at the upper guard (Eldjárn 2000: 326). This sword’s scabbard is wooden, inlaid with textile and covered in linen and leather; there are still several spots with visible profiled wrappings. There was a metal strip placed 12 cm below cross-guard, most likely used for sword belt attachment. The scabbard had a leather chape at the tip.

Organic components are also often present at type M swords from Norway. One of the Kaupang swords had a wooden grip wrapped with a leather cord or strap, and a wooden scabbard covered in leather (Blindheim – Heyerdahl-Larsen 1995: 61). Fragments of wooden grips and scabbards were simultaneously found with swords from Brekke (B10670), Hogstad (C52343), Kolstad (T12963), Støren (Androščuk 2014: 76, Pl. 111) and Åsland (C58919). The sword from Nedre Øksnavad (S12274) had a wooden grip and scabbard covered in textile. The sword from Eikrem (T12199), which is most likely of type M, had a scabbard made of spruce with parts held together by metal clamps and covered in leather and textile. The sword from Soggebakke (T16395) had a wooden scabbard. Swords from Hallem søndre (T13555), Havstein (T15297) and Holtan (T16280) had fragments of wooden grips. This is only a limited inventory that I was able to list during my short research. Yet it is an immensely valuable source that provides us with a decent idea of what the typical type M sword looked like.

Distribution and dating

When it comes to distribution of the swords, it seems that type M was mainly a Norwegian domain. In 1919, Petersen noted that that there are at least 198 type M swords known in Norway, of which at least 30 were single-edged (Petersen 1919: 117–121). Nonetheless, in the past 100 years, an immeasurable amount of new swords were excavated, and the number increases every year – such as in Vestfold, which is absent in Petersen’s list, we already have 42 finds (Blindheim et al. 1999: 81). Highest concentration of type M swords is in Eastern Norway and Sogn, where we know of at least 375 swords according to Per Hernæs (1985). Mikael Jakobsson (1992: 210) registers 409 swords in Norway. And current number will undoubtedly be even greater. We will most likely not be far from truth while claiming that type M is together with type H/I one of the most widespread Norwegian swords. The number of sword finds in neighbouring areas is disproportionate. From Sweden, we only know of 10 swords (Androščuk 2014: 69), at least 4 from Iceland (Eldjárn 2000: 330), at least 4 from Great Britain (Biddle – Kjølbye-Biddle 1992: 49; Bjørn – Shetelig 1940: 18, 26), 4 from France (Jakobsson 1992: 211), 2 from Denmark (Pedersen 2014: 80), 3 from Finland, 1 from Ireland and 1 from Germany (Jakobsson 1992: 211; Kazakevičius 1996: 39). Vytautas Kazakevičius (1996: 39) registers at least 9 type M swords from Baltic, at least 2 from Poland and 2 from Czech Republic. Jiří Košta, the Czech sword expert, denies there is a single type M sword find from Czech Republic and according to him, claiming so is but a myth often cited in literature (personal discussion with Jiří Košta). Baltic swords are rather specific – they are shorter and with a narrower single-edged blade, features causing them being interpreted as local product. It is safe to say we know of over 440 pieces, though the real count being much higher.

When it comes to dating the finds, Petersen argues that first type M swords appear in Norway around the half of 9th century and prevail until the beginning of 10th century (Petersen 1919: 121). Recent archaeological finds from Eastern Norway, Kaupang especially, show that they were being placed in graves during first half of 10th century (Blindheim et al. 1999: 81). Two Swedish datable pieces come from the 10th century (Androščuk 2014: 69), which is also the case of two swords from Iceland (Eldjárn 2000: 330). Polish finds can be dated to 9th century (Kazakevičius 1996: 39). Type M swords are thus widely present from both geographical and chronological perspective, and one can only argue if the similarity is just a rather randomness caused by simple design.

Generally speaking, a sword is a clear symbol of elite status and power. It is evident that Old Norse people, like people anywhere else, tended to compare to one another, be it in skills or wealth. This often resulted in quite a heated dialogue, in which men attempted to triumph in greatness of their qualities (so called mannjafnaðr). Swords undoubtedly played a role of wealth and status symbols in such situations. Looking from a broader perspective, one can find the answer in Norway that was multipolar in 9th and 10th century – ruling families were attempting centralisation, which resulted in creation of society with a strong feel for expressing its independence or importance through adopting the elitism model of sword ownership and its placing in graves. This led to Norway providing us with immense amount of sword finds, which is unprecedented. Social tensions affected everyone to a point, but only a few had the wealth to invest large in exclusive weaponry. “Simpler”, yet fully functional type M swords can be perceived as cheaper alternative that provided free men of lesser wealth with ability to improve reputation and identity of their families in times with no clear social stratification. This is supported by their look and amount present in both male and female graves (Kjølen, C22541).

„Simple iron parts without any precious metal decoration make up the hilt of the sword. It is a pragmatic sword, probably worn with pride, but not by the highest strata of society. Such simple and unpretentious swords seem to be the norm in mountain graves, and they were probably made or at least hilted in Norway.“ (Vike 2017)


Type M swords seem to be utility weapons that could had played a representative role to their owners. Two rare Norse swords – a sword from Strande (T1951) and sword from Lesja (C60900) – suggest that they were handed down for at least 50 years and were modified to match the latest fashion. This approach is also the case of other Viking Age swords (Fedrigo et al. 2017: 425). The swords from Strande has type E pommel, which was additionally attached to tang along with typologically younger cross-guard of type M (Petersen 1919: 78, Fig. 66). The sword from Lesja consists of blade with tang, to which a cross-guard of older sword style (type C) was attached together with type M upper guard (Vike 2017). It is also important to add that the sword from Lesja was found on an iceberg, where it most likely served a reindeer hunter 1000 years ago.

Lesja, Norway (C60900). Very well-preserved sword found in 2017 on an iceberg. Type C cross-guard with type M upper guard. Total length 92,8 cm, length and width of blade 79,4 × 6,2 cm. Thickness of blade 0,45 cm. Length of hilt 13,4 cm, grip is 10,1 cm long. Cross-guard measures 7,5 × 1,7 cm. Total weight 1203 g. Photo source: Vegard Vike, Museum of cultural history, Oslo.
