The symbol of knights and chivalry was the sword, representing loyalty and respect, and due the main inspiration of our noble Order came from the Spanish King Alfonso X, the Wise, also known as "King of the Three Religions", King of Castile 1221-1284 (Spain).
In his honor we have chosen his Royal Sword, with the noble name of "The Honor´s Sword"
Seven-Part Code written by King Alfonso X, the Wise :
Part II, Title XXI, Law iv: Knights Should Possess Four Chief Virtues
Excellent qualities which men naturally possess are called good habits, and are styled virtutes in Latin, and of these four are superior, namely, prudence, fortitude, temperance, and justice.
Although every man should desire to be good, and endeavour to acquire these virtues, not only the preachers whom we have mentioned, but others as well, whose duty it is to maintain the country by means of their labours and exertions; among them, there are none, to whom this is more becoming than to the defenders, for the reason that it is their duty to protect the Church, the monarchs, and all others. Prudence will enable them to do this to advantage, and without injury; fortitude will cause them to be firm and not irresolute in what they do; moderation will induce them to perform their duties as they should, and not be guilty of excess; and justice will enable them to act according to the right.
For this reason the ancients, by way of commemoration, caused arms of four kinds to be made for the knights; first, such as they clothe themselves with, and wear; second, those with which they gird themselves; third, those which they bear in front of them; fourth, those with which they strike; And although these are of many forms, nevertheless they are designed for two purposes; blows, which are called weapons.
And because the defenders did not ordinarily possess these weapons, and, even though they had them, might not always be able to carry them, the ancients deemed it proper to contrive one which should be emblematic of all these, and this is the sword. For, as the arms which men put on for the purpose of defence indicate prudence, which is a virtue that protects them from all evils which can come upon them through their own fault; so the hilt of a sword which a man holds in his grasp, is also suggestive of this, for as long as he holds it, he has the power to raise or lower it, or strike with it, or abandon it; and as the arms which a man carries before him to defend himself, denote fortitude, which is a virtue that renders him steadfast in the midst of dangers which may come upon him, so all the fortitude of the sword lies in its pommel, for to it is attached the hilt, the guard, and the blade.
And, as the armour which a man girds on is intermediate between that with which he is clothed and the weapons with which he strikes, and thus resembles the virtue of moderation between things which are excessive and those which are less than they should be; with great similarity to this, the guard is placed between the handle and the blade of the sword.
Moreover, as the arms which a man holds ready to strike with, whenever it is advisable, symbolize justice, which includes right and equality; so the blade of the sword which is straight and sharp, and cuts the same with both edges, represents the same thing.
On account of all this the ancients ordained that noble defenders should always wear the sword, and that by means of it and with no other weapon they should receive the honor of knighthood, in order that they might always be reminded of these four virtues which they should possess: for, without them, they could not perfectly maintain the condition of defence for which they were appointed.
