I have one in 440C.
It is a complex shape, so I will give you several measurements.
The tang of the drop point blade is 0.110"
Midway down the blade, the spine is 0.97"
Just above the bevel, the blade thickness is ~0.022"
One thing I have previously commented upon is that, because of the thinner edge, this fella cuts like a banshee and will outcut blades made of alloys with better reputations for edge retention. I am much impressed with the blade shapes on the GEC's I have handled. Truly, these are the products of designers who know their stuff about knives.
