Here’s a couple of custom tuning wrenches that I’m working on. The one on the left is made of Katalox, with Kingwood endcaps, while the one on the right is Olivewood, with Lacewood endcaps.

The wrenches are actually for an pair of autoharps, though the pins are the same. The style is a T-wrench, with an offset handle, sort of a middle ground between a gooseneck and a true T-wrench.
