Whistling arrow

The ones I have directly observed and most of the ones I have seen in clear photographs have the trailing edges of the holes proud rather than recessed. This more like what Jack observed. On the other hand it is quite common to have the leading edges recessed.

It is possible that the angle of a photograph might suggest that the trailing edge is particularly recessed when it is only in a channel directing airflow. Sometimes this is caused by the angle of the file used to make the groove. It is not so much a design feature as an inevitable part of manufacture.

Having written that, I have seen such a large number of designs that I would not suggest that your design is not traditional. Examining something in a photograph can be misleading.

The soundhole is also not drilled at 90 degrees but angles back toward the fletchings to give a sharper edge.

Great, there is progress.
Bede, I think I now understand better what you actually meant by recessing the holes.

Jack, in my case the soundholes are atually drilled at an angle and than the trailing edge? of each hole was shaped to be more or less parallel in relation to the arrow shaft. I hope the description is clear enough...

By leading edge I mean the edge which the wind passes first. The trailing edge is closer to the fletch. The sound is made at the trailing edge.
