A couple years back, Ivan traded two Spydie folders (the infamous, or forgotten, 666 model lum chinese and...one I don't rem) for an Esse he was working on at the time. #5, it is. He even let me choose the type of handle materials that I wanted. It was a great experience! He was great with everything, including the shipping, and explaining to my addled brain the best ways to ship stuff to him.
It is seriously the sweetest knife I have. Honestly, it's too nice for fella like me, so it stays safe and sound away from the grind o' life.
Very, very well made knife, IMHO, limited as that opinion maybe. Again, he is a great guy to deal with.
