Cannot recommend anything in particular, but keep us informed what you find, I have also been interested in 5/32 blades, during a time when I was considering what would be a good thickness in a overall knife. For me, 3/16 was too thick, went with a AA forge camp knife in 1084 in 5/32. Finally decided 1/8 meets my desires and what I looked for in future knives, not to dissuade you in your search. Can you give us your reasoning in wanting that thickness? Intended uses?
