Where there is typically nothing different about a blademasters sword. Upon proving their mastery of the blade and the many sword forms, they receive a blade with a special mark to signify their achievement. (This mark is dependant on your DM and the campaign)

Sometimes this blade is specially commissioned or made by their master and teacher. Other times this marked blade is received by winning it from another blademaster in a duel. Still, other times the blademaster receives their blade as part of an inheritance, and after years of training and practice, they are finally worthy of the mark upon the blade.

If the blademaster is being used in the campaign, the mark is usually recognizable to most people. Commoners will often be wary of the blademaster, while others proficient in martial fighting my challenge those who bear the mark to a duel. Due to this dynamic, those who carry a marked sword do not do so lightly, and those who carry it fraudulently, usually do not for long.
