GEC definitely has some greatest hits... This list is inevitably subjective but I think many will agree that some patterns are more popular than others.
#15 in almost all iterations, #23 large trappers, #33 Conductor, #35 Churchill, #47 Viper, #48 trapper, #66 serpentine, #68 White Owl, #72 lockback, #73 Scout, #74, #77 jack, #85, #92 Eureka...
Then there are a great subset of patterns that are beloved by some, but may not have been around long enough or be universally popular enough to be in the top category. Knives like the #14, #25 mini-barlows, #38, #53 and #54 equal ends, #62, #78, #81, #86, etc.
And then there are the niche patterns... knives that either haven’t been run in a very long time, or just aren’t that currently talked about, like the #06, #09 Esquire, #18, #61 Congress, #89 melon testers, #97 Wall Street.... basically every other pattern they make. And not a single one is a “bad” knife.
