After a lot of thinking, I think a using blade, a Mini skinny Trash would be a really safe bet. 4.5 inch blade, 4 inches being cutting edge with a half inch choil to allow choking up if wanted. Maybe .150 to .170 thick blade (.187 would work) with a war dog handle. ANY handle color besides black. OK, black also.
