ARMOUR-plated crustaceans, huge sharks and spiky John Dorys are no match for the flashing knives of these expert fishmongers.
The team from Huddersfield's Sailbrand fish merchants off Leeds Road scooped a clutch of accolades at the National Federation of Fishmongers' Craftsman of the Year contest in London.
Although much seafood is processed mechanically, filleting skills are slowly coming back into vogue.
Production manager Andy Thornton won the sea craft challenge at the event by preparing a variety of fish within a time limit.
Filleter Peter Preece, who won the title two years in a row, this time came third in the shellfish category, second in poultry and fourth when it came to preparing Scottish salmon.
"There were more entrants than they've had for quite a while," said Mr Preece.
The contest has run for over half a century.
"People from Huddersfield have won quite a lot down the years," he added.
Graham Dyson came fourth in the sea craft challenge, just beating Jady Mir, who came fifth.
The competition tests butchery skills, presentation and yield of meat, sometimes off tiny bones.
The successful Sailbrand team walked away with cash prizes, medals and a selection of knives.
