Wiremark export and wire distribution product sales manager Andy Macdonald said the outcome was disappointing.
The Golden Pliers was a renowned event which attracted top quality competitors as well as international spectators who watched Kiwi methods and techniques, he said.
"It's the world's largest fencing event and the Golden Pliers is the most prestigious event recognised around the world."
Wiremark would review its position next year if there was a "sufficient level of engagement and organisation".
Fieldays fencing committee member Craig Graham said elite fencers had boycotted the competition and only one senior fencer had entered.
There were only seven entrants, compared with the usual 30-plus.
One of the fencers had been in the trade only four months and the others were so junior that judges removed a requirement to hang a gate to avoid "embarrassing" the entrants.
Mr Graham said the Golden Pliers was equivalent to the Golden Shears, a highly sought after trophy which gave mana to the winner.
Even just being a finalist guaranteed more work.
A 14-time winner of the Golden Pliers, Paul Van Beers, said fencers were so disappointed they were pursuing other venues to hold the competition, and the Hawkes Bay Show in October was the likely option.
Strainrite Fencing Systems director Maurice Wooster, another sponsor, said international buyers at his stand indicated they would not return to Fieldays without the Golden Pliers.
Fieldays events manager Vanessa Richmond denied that some events at Fieldays were given more attention than others.
