Sorry to hear you had a less than pleasant experience, lambertiana. I'm really hoping I don't have to go through too much hassle.
Some more observations. If you go to KnivesShipFree's page for Mini-Canadian in 20CV (
click here), you will notice two things:
1. Some of the knives (like mine) are horizontally stamped on the blade, while others are vertically stamped on the choil area
2. All pictures of blade-stamped knives have a distinctly different background from the choil-stamped ones
As such, one might reasonably assume those were two different runs. Furthermore, if you look at the spine shot of a blade-stamped knives (
example here), they
appear to be somewhat thicker than the choil-stamped ones (
example here). As noted before, the specs on KSF indicate the A2 Mini-Canadians have 0.150" blade stock, while the 20CV Mini-Canadians have 0.125" blade stock.
My calipers have shipped today and I should be able to add more information to this discussion by the end of the week.
