Never base a decision on the advice of those who don't have to deal with the consequences.
I have a couple of kitchen knives in progress, a Chef's Knife and a large kitchen utility. They are both about 12" long and are made from ultra thin .049 15n20 Steel.
I have some .070 Titanium and a carbide applicator coming in for some carbidized Ti Chef's knives! I also plan on getting some 3/32-1/8 steel for some more conventional chef's knives.
As a former chef I like a wide variety of knives in the kitchen, this thinner stuff will be slicer city...
