Traveling Tool Kit: ret Slot Cleaning Hook

I made this tool years ago by grinding a 12mm wide violin maker's knife into a little hook shape. It's virtually impossible to see in this photo, but the very tip is slightly hollow ground so it's widest at the pointy end, which I keep very sharp. With it, I can drag glue and debris out of a fret slot, and deepen it without injuring the sides of the slot. A similar and equally effective tool is available from Stewart MacDonald.
