Hi Terry,
One factor that does come into play is name recognition. The most honest judge is going to be influenced ever-so-slightly by a knife made by a big-name, popular maker. It's up to him to overcome this impulse. Good judges have no problem with this. Some shows cover the makers' stamps with tape. I think that levels the field a little bit.
As you can imagine more times than not when I am judging there are not only makers I represent as a dealer...but they are friends of mine as well.
For me, I am probably harder on the guys I represent than the others in the competition. There might have been a time that a makers name would have influenced me ever so slightly. I was cured of that after judging for a few years. I became so disappointed in seeing the "Big Name Makers" work with so many mistakes. They showed me that they were now resting on their laurels and felt that they could submit anything and win.
A funny story with regards to this. I was judging at the Las Vegas Classic knife show, probably 15 years ago. Harvey Dean had delivered 3 Bowies to me at that show. Later on he submitted on of his Bowies in the Best Bowie competition and he won.
Later that day he pulled me aside as he felt there may be some repercussions as he delivered 3 Bowies to one of the judges. I tried to stop him a couple of times and he just kept talking.
Finally, I said "Harvey, it is ok....I voted for Roger Green! We both had a good laugh. But his point was well taken.
A friend of mine submitted a knife, beautiful dagger. The other two judges voted for this knife...until I pointed out that the edges were not symmetrical. On one side the grind was probably off a 1/16th of an inch. Someone else won the best art knife award.
I was talking to him after they announced the winners. He knew I was a judge and asked me why the other maker won the award. I explained to him what happened. Needless to say he was pissed at me.
I explained to him that a world class maker such as he is should have never let that knife out of his shop...let alone entered into a competition. I explained to him about how I was so disappointed in earlier competitions I judged that the big name makers were submitting knives with so many mistakes.
That I represented him and I was not going to work with a maker who knowingly let work like that leave their shop....and that thought it was good enough to enter into competitions. As that is the beginning of the end.
He removed the knife off of his table. Took it home. I saw him a couple weeks later...the blade was perfect. He entered it in the best art knife competition and he won.
No, I was not a judge.
Im happy to say he is still a world class maker, he is still winning awards (two at a recent show) and he is still my friend.
I can only speak for myself. Tape over the name is not necessary...the knife (regardless of the name on the blade) speaks for itself.
