They don’t show any views with the jaws closed. It looks to me like the cutting blade sits back from the edge of the anvil side. This means you can’t make a flush cut. I also wonder how robust the blades are. I get the feeling that even the slightest twisting force could break them.
They arn’t cheap enough to buy and try.
I’ve used Linstrom cutters for at least 40 years and don’t see any reason to change.
