On most holes, there is something of note. When they use a laser or a plasma cutter to cut the blade out (of a large sheet of steel) and to cut the hole out, there has to be a starting point.
Usually the whole outside of the blade is finished, so you won't notice the starting point of the outside of the blade.
I think Taiwan will grind the inside of the hole flat, so it will look satin like the rest of the blade, but some factories don't finish the inside of the hole.
I'll get mine out a little later and give it a good examining. Where exactly did you say it is? First you say vertically down the Spyder Logo, then you say from the Hole to the Edge. I think I see something in your pictures, but it just looks like a grind line in your picture.
A distinguished lurker.
