How Much Is A Well Used Flat Grind Sebenza Worth ???

[nyefmaker]

I will try wording it this way since it seems like the way to go! I am in the process of working out a trade and would like to know what it is worth ? I have seen the pics and will not post them as they are not mine to post. The sebenza is a large regular flat grind, unsigned. It has been EDC'ed for 5 years and has been sharpened. I think these might have had bg-42 steel, but not 100%. I know what mine is worth and would like to know how much the sebbie is worth so we can work out a fair deal. If I need to add $$ ?? I look forward to you responces.
Thanks In Advance.
