Bought a heavy duty Rapala electric fillet knife at 1st. Monday a few weeks back . fellow said it ran good but blades were messed up (both sets ). According to him the blades would separate as soon as you hit the power button . Figured it was worth the 10.00 for a backup so I took it hoping my blades would work .When I got home it was obvious he had the blades mismatched (7 inch/9 inch ) Yep , he does vote ! :Rofl
