Fit and finish is excellent. The blade looks like it is hollow ground (you can see this in the pix) but is actually forged in this configuration. It is more than 7/16 inch thick at the back of the blade but narrows to about 1/4 inch or perhaps a bit less at the center of the hollow grind. The edge is perfectly hardened -- near 60 Rc in the chopping area and softening gradually toward tip and toward cho. Excellent rig and a best buy.
