Handy Little Tool
I have one of these on my keys. I use it all the time. The blade holds an edge well, the file may work on your nails or other soft material. I have used it maybe only once or twice on soft wood. The tip works well as a flat head(and in a phillips if you can get it to fit). I did loose the tooth pick, and tweezers after a while.
Over all I am very happy with this product.
