Top one is 1 of 4 of the Ban Tang/Horton Collaboration BT4 LE with Carbon Fiber Handles. The bottom one is the very first compound grind BT4 Compound Grind with tapered tang and Maroon Linen Micarta Handles. Those are very vintage for sure. The compound grind BT4 was actually my personal knife for a while. Take good care of it.
