Here's a pic of my flag-based kami marks. All were taken from the same point of view with the handle at the bottom. The Kesars were purchased in February and March of 2002. The Durba was relatively older, I don't know when it was made. The Muralis were purchased within the last 4 months, with the initials as well.
As you can see, the Kesar "flagpole" is oriented toward the cutting edge, flag tips toward the bolster, on the left side of the knife if viewed in the chopping position. The marks seem made of single strikes for each line. The flag is made up of almost equilateral triangles.
The Durba flag is oriented the same way, but is relatively smaller (the scale of the GRS throws it off a little). The lines are made up of small marks in a row. The flag is slightly different as the chevrons overlap and are closer to right-angle 3-4-5 triangles.
The Murali flagpoles are toward the bolster, with the flag tips towards the cutting edge, on the right side of the knife. The marks seem made of single strikes, but the chevrons are right-angle triangles but are not overlapped.
I'm doing an inventory tonight for my records so I'll have another post showing other kami marks.
