R151B; The Roselli 5" Leuku is a stout wilderness blade. It's about 5 1/2" long, 1 5/16" wide, and .200" thick. It's not too unwieldy for general chores and heavy enough for light chopping. It has a steel rod welded to the tang for those who like full length tangs. If you prefer the usual Roselli short tang just cut it off.
