I bought some AI tools, and the #2 left and right bent skews were different widths than advertised. I don't consider that as any sort of failure on their part, since the tools are hand made. Back when I was working for a living, I'd rake the machine shop over the coals if they did that on one of my designs, though. The carving tools I bought from AI were ready to use right out of the package.
