in my travels around the aleutians i never saw an aleut with a long knife or sword, maybe a harpoon, american hunting knife or a ulu but no long knives. there may have been some on dutch harbour where the japanese had an outpost dug in for a while, but we were discouraged from walking around there due to unexploded ordinance (ie mines). the aleutians belonged to russia before we americans bought them from the tsar.
aleuts are the Unangans, the related Sugpiaq from the kodiak area are also called Alutiq but will not be upset to be called aleut (aleut was a russian designation)
Ulu:
some earlier ones, they'd make them of polished slate, bone, etc.
also used a small 'crooked' knife for carving items like kayaks, bowls, etc. some with rather fancy handles much larger than the blade.
