This is a very hard to find tool, even on the net. It is a four sided pyramidical shaped awl. It fits easily in the hand and is one of those simple and inexpensive tools that one simply cannot do without! Well, I can't. It is otherwise known as a birdcage awl from the days of yore when men still made wooden birdcages and this little tool really excels at its task.
For starting screws and a millennia of small hole applications, simply put the point on the mark push lightly and swivel...that's all there is to it.
I fully recommend this quality product from Narex. (And no, you won't find one from any other supplier in Southern Africa!
