  • Probably going to be buried with it.
Color: G: 7'' flex fillet knife
I've fallen in love with this maker. I've built a small collection with this one as one of my favorites. It is razor sharp and nicely flexible. It is strong and has a good size, well made handle. Down side: you'll probably gain weight from wanting to use this knife every night to cut up then consume some good meat. Pro tip: get a sous vide machine. ... show more

Nice knife. Handle feels good. Not sure what is made out of lead on it per CA 65 warning on back of packaging. Not seen that on a knife before. Got babies, be warned. Also made in China. If that matters to you.

  • Absolutely worth the buy
Color: G: 7'' flex fillet knife
Son absolutely loves this filet knife because of how much more flesh he can get off the skin when he filets panfish. It made such a huge difference. 3 panfish was enough for 2 people, which is crazy. Normally we were getting such tiny filets, but the control this knife gave was exceptional. Worth every penny. Haven’t had it long to say how it will hold up, but he had another one from this same line that is bigger (for the past year), and it is holding up great! ... show more

  • Great Fillet Knife

A very sharp, flexible knife perfect for filleting fish. I having used it yet, but it’s everything I hoped for at a great price.

  • Flexible sharp filet knife Flexible sharp filet knife
Color: G: 7'' flex fillet knife
I bought this to filet pan fish 8-12 inches. My old knife is sharp but rigid so small filets were hard for me to accomplish. I chose the 7” model because it seemed to be the most popular size. My first impressions are that this is plenty sharp and the flexible blade yielded the filets in the picture with ease. The handle is comfortable and gripped well when slimy. I like it very much so far. ... show more
