Your favorite cover (handle) for your EDC

[BenHarris]

As a blue collar guy (masonry, carpentry, etc), I'm all for delrin. I can drop my Case Peanut, my Boker Barlow, or the like from a ladder and not worry about split bone handles.
For the days I work for the church, I am very fond of jigged bone.
