For what it is worth, I have has asked this question a number of times (on other boards)and have not got a satisfactory answer. Help me out if you can. First, let me explain this. I clean alot of fish throughout the year and use an electric filet knife (I give away alot of fish to people who like to ear fish but are unable to get out and fish). Thus, my skill with a hand knife is poor. What I am looking for is a cordless filet knife that I can use on my fly-in trip up north. If you look at it, we have cordless for everything else, why not a filet knife. I just know there has to be some out there. Can anyone help me out as what brand(s) there is/are and where I can be purchased? By the way, went fishing Friday and caught and kept about 50 crappie (lost a bunch and threw some back). Went yesterday and caught about 30. Total for both days included about a dozen 9 inchers and the rest were between 10 and 12 inches. Another reason for getting out was to check the boat out and it worked great. Ready to get back in the groove as soon as the weather cooperates a little more.
