Any knife collectors on here?

I have become one and am starting to get into the finer aspects of sharpening. I love reading about the different steels and their use......Interesting stuff that I really had no idea of this before my buddy starting explaining it to me. Now when I see any knife I want to know the steel type and grind..including kitchen knives.
I really enjoy the folding Spyderco brand and have collected fixed blades, survival knives and parangs from other manufactures as well. Seems I always have a cut that's healing from playing with them! :)
