I finally took detailed measurements of two of my dha of this style. The first is the one in your first post (
DRI #0049;
HOS #250).
Blade length: 50 cm
Handle length: 31 cm
Blade Width (height)
at base: 10 mm
at narrowest point (about 8 cm from base): 26 mm
at widest point (essentially at the tip): 40 mm
Spine thickness
at base: 10 mm
at 1/3 length: 4 mm
at 2/3 length: 2.4 mm
1 cm from tip: 1.5 mm
As you can see, the blade taper is very dramatic at first, going from 10 mm to 4 mm over the first 1/3 of the blade, then quite gradual for the rest of the blade.
Then I went kind of crazy and made detailed measurements of the handle sections, noted in the photo below (all measurements are in millimeters).
