That's the blade this man has. The clients house looks like a blade museum, I agree with the blade length. That's the sweet spot for me. That is a pricy though! I don't really have a collection I use every one of my knives, there is common patterns I have but not really a collection. At this moment in look to off-loading half my blades.

And yes, I wanted one. Pricey for a knife that is waay to large for EDC. I don't like to collect for the sake of collecting, and 2.75"-3.5" blade length is my sweet spot.
