I'd definately like to see some of the smaller blades to be thinner. The Dumpster Mutt would have been great if it was 3/16. I guess that explains why I love the RatManDu so much.
In general I doubt I'll be doing any chopping with the any of the 6 inch or smaller knives. In that regard I'd much rather have them be slicers and have dimensions and geometry that reflect that.
