Hey wow,
We need more info. Such as blade length, blah... blah... blah...
Are you looking more for conceal -ability or function? If your looking for function, and to a degree conceal-ability, I would go for a full bevel ground Model EB. You can choose between short or long versions, (long version has the addition of a pseudo-subhilt). You can also choose between spear point and tanto.
If concealment is more of an issue, I would go for a Model AD or DB.
Give us a few more details and we'll do our best.
