There is no "real" difference between a "Viking" sword and a "Saxon" sword in the period your interested in, 800-1000 AD.The only types that would not be common , for a Saxon, would be the wheeler type 2 hilts, which include the peterson type,A,B, C, H, and I. This type hilt is rare in a Anglo-Saxon context. I think one possible wheeler type 2 has been found in England.It has become the common view that the type L hilts were exclusively "saxon" but many more of this type have been found in Norway.(around 40 IIRC) than England. The only real difference in sword of this period would be in the hilt decoration, and that would be slight. The predominant form of decoration was wire inlays in geometric patterns, which were used all over europe at that point. and because of trade, plunder, etc, this would have blurred any distiction between a Saxon , viking, frankish, balkan, etc. sword.A simple answer to your question ...the less expensive Albions that viking shield sell would be a route, The best choice would be the "clontarf" this type (K) dates to @800 AD.This sword is copied from a sword found in Ireland..but it has purely Frankish decoration, and could have easily found its way into Saxon hands,.Many 8 century Saxon swords have very strong resemblences to type k', (fetterlane SP? for example) but that is a a different topic.The vinland (type R) or the gotland(type Z) would both be appropriate for later (post 900) swords as both types have been recoverd in England.Also the period 800-1000 AD is a pretty long time, and the typical Saxon Warrior, or member of the fryd , would have become much better armed over time.

Way of thread..... but

The Fransisca, the axe commonly associated with the Franks appears to have fallen out of use amongst the The Merovingian Franks after about 600, see 'The Pace of Change; Studies in early medieval chronology' (Cardiff Studies in archaeology), and reappear to some extent during the early Carolingean period.

The fransisca appears to be used by the Englisc for a short period after it fell out of favour with their continental germanic cousins.

The Byzantines at the time of the First Crusade appear to call anyone from North Western christendom 'Franks' irrespective of where they came from, Scots English, Swedes,Germans, French etc.
