Fish Caught: WalleyeFor atleast 15 yrs I have owned the green Mister Twister Electric Fisherman fillet knife and with it have cleaned literally thousands of perch, hundreds of walleye and more salmon than I can count. I was amazed with my recent purchase of the Piranha. I first used it on Chinook and Coho Salmon this fall and I produced the cleanest, quickest fillets ever. I didn't think anything could out produce "old green", but you did it. Now I own two favorite knives. The only downside was this fall, after my friends and I finished fishing and they saw my results, I had to clean all their fish as well.
