For speed, try an electric fillet knife

Old-style fish cleaning with a traditional fillet knife is effective. But for anglers looking to minimize the time they spend in a cleaning house, an electric fillet knife is an upgrade. These gadgets allow for faster, more exacting cuts, and they clean up quickly. Best to scope out various models and read their online reviews closely before purchasing, however. Quality varies. And while plug-in models are cheaper, those with rechargeable batteries are more portable.
