I own a sword. My husband and I bought it at a Renaissance faire and displayed it on our wall for a few years. Sadly we've had to lock it away in a gun cabinet (how weird is that?) because we now have two young boys. Having a real sword available to boys while they grew up seemed to be a bad idea. I imagined coming home to a reenactment of Spartacus, and had to put my plans of sword collecting on hold.
I look forward to the day when my boys have moved out and I can pursue again my desire to establish a sword collection. This fascination started when I was kid and my parents took me to the Field Museum of Natural History in Chicago. Among a multitude of other amazing collections, I found a hall of Medieval and Renaissance armor and weapons. I remember staring at huge double-handled broadswords and wondering if they had actually been used to kill people. Gruesome, I know, but antique objects always inspire me to imagine their stories.
At about the same time in my life, I became enamored of fantasy fiction. I'm guessing that swords have strong appeal to fantasy readers. I know I find it delightful to have one or more hanging on the wall. Along with being attractive (to my taste) I can fantasize about being someone of a noble lineage whose home is adorned with the weapon heirlooms of her great family.
For people desiring to start a sword collection, I recommend a visit to my website Sword Buying Guides & Symbolism. I'm hoping someday to use the advice at that website myself.
