Well, I always liked to branch out a little, not only go for the swords, but also other stuff. Maces, axes, daggers... sooo many daggers... though I guess some of them might qualify as short swords... a speartip I really need to mount on a pole someday... even have a bow built after medieval patterns, though I prefer my old sporting bow if I want to have fun with arrows. The replica is old and made of wood (duh) and so I am not sure I could trust it in operation... but its still neat to look at.
Oh, and two staves. Since IRL I am definitely more the brainy magica character type rather then the athletic stamina character type (that would be my brother! He definitely would make a good rogue!) So... robes and staff I guess?
As for Axes... well, a mediaval replica viking bearded axe is not too hard to find, and cheap too (since axes need far less high quality of fabrication then swords). And its easy to costomize with adding stuff... (still looking to do more of that for mine, I have some thread wrappings to secure the axehead, but would love to add some nice leather bands along the shaft...)
As for longboats... well, those do seem a bit lost without water to float on. Although the vikings did occasionally cross land to go brtween waterways, dragging their boats on log rollers... viking boats generally were on the small and light side compared to other ancient rowing ships. Not in the least because vikings sailed into narrow fjords I suppose...
Anyhow, a lifesized one might be a bit of a project, considering they were what, 12-30 meters or so?
Still, there is a lot one could do I suppose... even build a boat on grass and pretend its weaves if someone really put their kind to it.
