Well, my various collection is only given names to differentiate them, but it is more a description than anything else. For example, my Kojiro Sasaki suburito is refered to as Kojiro, my sunuke bokken are refered to as the sunuke, my Kukishin bokken are refered to as Kuki, my Togakure Ryu bokken and Mogito are refered to as the Togakure (bokken or mogito), and so on.
How I view them is defined by what the circumstances are. If I am just thinking of them in the abstract (not using them at the time), then they are tools, used to cut away habits and aspects of my behaviours to reach the core essence of myself (how I view training in general, a sword just makes the "cut away" metaphor work better...). When actually holding and using the weapons, I tend to not think of the weapon itself. I simply strive to achieve success in the circumstances, and that involves the sword, whether it is the perfect exectution of a kata, solo or paired, or a more free-responce training where the concepts are far closer to combat, and success is defined by survival. The sword is simply the means I use. I have many others, so it isn't my highest or only option. Personally, I love spear. Now that's fun.
