Aaaaaah, NOW I see what you all mean! There
is indeed a difference between the sides! When I hold it in my hand, spine up, the convex side is on the right, while the left side looks flat or I guess what you could call concave. It's just, that in my minds eye I imagined something more dramatic akin to a straight razor. I see now that it is more subtle and I also notice that the whole blade actually curves slightly to the left. You can even see it on the very tip too, but that is unfortunately out of focus on the last pic above.
And yes yes, pictures!
