I originally used the Big Game Skinner Blade, but I have a natural instinct to extend my index finger when ripping a hide open. It only took one time to learn how sharp the back of that blade is. I switched to the Marine Blade and highly recommend them. Unfortunately, there is not a 5-pack replacement set on the web site. I called and left a message and received a return call the next day. She confirmed there is no 5-pack, but offered to sell five singles at a discounted rate. I also prefer the five inch Mano blades instead of the three inch blades, and ordered some of them. I received my entire order in the mail and I am very satisfied with the products and the customer service.
