Need help with electric fillet knife
Hello, hope somebody has insight! I have a Rapala corded electric fillet knife I bought several years ago and it's worked fine. I think it was called the heavy duty model, it was about $60. This season, it kept working worse and worse and I assumed it was the blades. Tried to sharpen them but it didn't work. Bought a new set of blades and was surprised... I don't think it is any better. The problem is cutting through bone. This is bass. I make the first cut downward through the flesh no problem but when I turn the knife to follow the backbone like I always do and cut through the ribs, it cuts awful. Just doesn't seem to want to cut! It seems I have to make a sawing motion with my hand to make it through, lol. Something is clearly not right as I have filleted a bazillion bass in my life and, as I said, this knife used to work ok. When I look at the blades as I press the button to have them make their motion back and forth against one another, I do not detect anything different from the way it used to be. What the heck? The only other thing worth mentioning is I detect the knife getting a little hot and I do not recall that warmth before. Any ideas?
EDIT: I have filleted about 120 bass in the past month with this knife and they are, generally, 1.5 lb. to 2 lb. fish with a handful being 2 lb. to 3lb. And if I had to buy another, I don't know what it would be. I have seen threads about how great American Angler brand is but then people say they are not what they used to be. When I was young, I used Mama's ham and turkeyu carving Hamilton Beach and it worked fine, lol.
