A Quote from Lexi Alexander 
Director Punisher War Zone
"When I had to decide on an "official" Punisher knife for our movie, I chose a RELENTLESS knife out of thirty knives that were put in front of me. We all agreed it looked the best and felt most authentic for the Punisher.
Then I inquired if I could possibly get the knife a few sizes bigger. Dan Certo of RELENTLESS  KNIVES USA offered to produce a custom made knife for the PUNISHER. When it arrived, it was as if someone opened a jewelry box with a 5 karat diamond in it. The entire cast and crew stopped to admire it. Needless to say, Ray Stevenson aka Frank Castle was in heaven and we the filmmakers liked the knife so much, we gave it its own close up in the first five minutes of the movie.
Dan, you are an artist!
