These three are quite special for me for the people they remind me of.

The boner with 4 3/4 in 15N20 blade has scales from a walnut tree I felled on my late fathers yard in the early 80's.

The light hunter with 3 5/8 N690 blade has buffalo horn bolsters from a friend in South Africa and end grain olivewood given to me by a retiring knifemaker friend.

The field scalpel with 2 3/4 N690 blade has buffalo horn scales from a few horn tip given to me by a friend in the US.
