I need to know if a Model#1-7 is consider a large blade. I need to have 2 lines of etching. The catalog states that you are allowed 18 spaces per line and 2 lines on large blades. Can you get special characters like a forward slash and roman numerals? I am trying to spell a specific unit and rotation and would this count as one of my chargable options? I know you guy's are the one's to ask. My last question is if you can send knives back to RMK for etching and what would be the cost and details? Thanks, Jimmy
