>He says that doing the holes this ways have more advantages that the
classical straight auger in the middle of the box.

Being able to spot your equipment at a glance also comes to mind as theft is
a reality these days,

We do a modification to our pallets which is not standard which makes our
pallets recognizable at a glance.

I have moved away from branding all the boxes in favor of stamping all new
frames going in service. Rubber stamp. I picked up the method from Bell
Honey in Florida as they are always selling equipment and buyers balk at
newer branded equipment but don't seem to mind stamped frames.

In California frame theft is greater in my opinion than hive theft. We have 
lost frames as has many others.
Harder to detect these days with grooved top and bottom frames and plastic 
foundation hence the rubber stamp solution. In the days of wired frames each 
beekeeper had his own style.
( usually the placement of the wire hold nail)
If offered hives with frames which have paint across the top most likely the
frames are stolen stamped frames. I have been told a coat of paint will
cover the stamp and no way to tell what the stamp read.

What do others do make their hives identifiable if stolen?
