I'm trying to recall the name of a knife I saw a few years (4?) ago. It was made by Al Mar Knives. Was a folder with a liner lock. Had a slender 6" blade and was around 12" open. Opened via a thumb stud, believe the handle was either aluminum or zytel? Handle was black and ventilated. Might have been in an article from the now defunct Fighting Knives. Believe it was their largest folder. Police back up knife? Thanks for the help.
