My history buff friend informed me as I was about to erase it that it is not just the symbol of crusaders

It is a simple geometric figure that adds a little something to the blankness of his clothing/shield/etc. and BTW, the knife is not meant to be useable, it is a decorative given him (in the story I am writing) by his king for saving him in a battle. It is a known symbol given to few, and is meant to be small. Also, the shield is small because he depends on speed. His boots/shin armor are made of light metal and made mainly for slashing protection and also if he drops to his knee(s). He didn't use leather because the metal looked more uniform with the other people, and seeing as he is a Royal Guardian, the group of about 15 people who serve as personal bodyguards to the king, he likes looking uniform.

I could explain him inside out, but you can wait til i write the story. It is not PS based, BTW.
