In my scattered records of past sale results, I find a 6" H. BOKER USA with adjustment lock -- the image file showing it is stored on a different computer than the one I'm currently using for web & email work but I may be able to get that image attached to this note sometime later. (I have 8 hrs at the cash register this afternoon & evening, plus getting ready to work with "Bus" tomorrow to ship out auction catalogs to his list of recipients. )
I have BOKER pliers & scissors -- the markings are all stamped which suggests they were using contract production sources rather than having their own manufacturing plants.
