I am looking for medieval Russian swords (especially from western Ukraine and Belarus) from second half of 13th century to the beginning of 14th century.
I would be very grateful for all your help

I do not have any pics for you this moment, but the Russians themselves would use either a typical European sword of the era ( Oakeshott XII, XIII, XIV, XVI with usually a wheel pommel of some sort ) or one of the later variations of the "Viking" lobed pommel. The Mongol Golden Horde was present in Russia at this time, so straight mongol sabres were around, but iirc the Russians themselves had not yet widely adopted it. I'll try to find you a link to some pics. I believe that the Osprey book on medieval Russian armies has some good drawings of some swords found in Russia, including iirc a large type XIIIa with type 2 cross and octagonal faceted type I pommel.

Most of those swords are from Poland and State of the Teutonic Order. But thank you anyway.

Would any of these be Russian? http://www.tforum.info/forum/index.php?showtopic=21351

A N kirpitchnikovs works are the way to go for russian stuff up to the 15th century.

i didnt look at his stuff on swords all that much. but remember around that time period a few things happened,

first up, the mongols.. big consideration.. and
secondly, there was conflicts with the swedes and teutonic order. another influx of weapons.

but f i remember kirpitchnikov doesnt mention much about russian double edged swords after the 11th century.. i get the feeling russians might have very heavily adopted the sabre after the 11th century..
although it was being used since at least the 10th century when the rus adopted it from the khazars.

their double edges swords would, i think have been quite similar to west european ones in terms of designs maybe though aim for what was used in scandinavia/ eastern areas of germany/ poland/ hungary
