I was just in Forest City Surplus in London and discovered Rapala batteries for the cordless fileting knife as well as a 12 volt adapter. If my eyes were correct I could have sworn they were .99 cents. Since I already purchased 2 more for a lot more than .99 cents I don't think I need more at this time. Just letting anybody know who has the Deluxe Cordless Fillet Knife Set. Merry Christmas and good ice fishing in the new year!!!Dave
