how thick are each blade 3/8 inward from the apex?
I have measured from the cutting edge up onto the primary grinds of all 3 blades, realizing that is probably the info. you want and it is as follows:
Both of the machetes measure 1/8 of an in, 3/8 of an in. off of the cutting edge. The Siegle measures 5/16 of an in. The difference is that on both the Collins and the Siegle, the measurement is being taken well up on the flat of the primary grind, where as the Svord is convexed well up to 1/2 of an in. off the edge, thus shining a light on it's ability to penetrate.
Thank's for asking SM, the measurements give me a little information to file away.
