MY GUESS WOULD BE A LETTER OPENER DUE TO THE SIZE. MANY COMPANYS MADE ADVERTIZEMENT LETTER OPENERS ,WATCH FOBS, POCKET KNIVES ECT. TO GIVE TO GOOD CUSTOMERS. THE RIB DOWN THE MIDDLE OF THE BLADE LOOKS LIKE IT MIGHT INTERFERE WITH LETTER OPENING BUT OTHER THAN THAT IT SHOULD WORK GIVE IT A TRY. NICE ITEM
