My name is ***** ***** I would love to help. This is a Romo Japan Stiletto single blade, faux button manual folding dirk with black composition handle. This looks like model J-259. The value of this knife is $30 to $40.00 retail.
The valuable Romo knives are the ones marked Romo Italy with brass, black horn handle and working buttons. These are worth $300 retail.
