I'm a big fan of GEC! I just "discovered" them a few weeks ago and I have 5 already. I'll go through what I have and what I like and dislike about them.
1) Tidioute Scout (#73) double blade trapper with green cut bone. This is the knife that really set the hook for me. There's a lot on the plus side of this knife. It's gorgeous- with crisp jigging, great color and beautiful lines. It's built like the proverbial tank, it has great heft without being too heavy. The blades have excellent grinds and are crazy sharp- they remind me a lot of Bark River's blades, except they're in a folder. The blades have nice snap, and the flush joint is lovely.
On the minus side- the backsprings really are too tight for my taste. I think it's something you can get used to though.
2) Northfield Scout #23 single-blade trapper in "Brimstone Bone". This one is a real looker. With the over-the-top coloring and deep, craggy jigging, this may be the best looking knife in my collection. It is a good deal thinner and lighter than the double-bladed model. It is comfortable in the hand, and the backspring is not too tight- they got it just right. I love this knife. No minuses on this one.
3) Northfield Pioneer #23 single-blade trapper in "Brimstone Bone"- matching serial numbers with #2 (above). This is very similar to knife #2, except it is quite a bit bigger. It is relatively thin, and isn't too heavy. I think this is basically a "Mountain Man" pattern. I like it a lot, except it is too big to carry legally where I live. And the jigging is just a hair less nice than the #73 version. The backspring is nice on this one.
4) Northfield Barlow #25 with tan sawcut bone. It is a very nice little knife. It is a tad smaller than your average Barlow, and has a great feel to it. It's a departure from the normal pattern in that it has a small clip and a large spearpoint instead of the usual small pen/ large clip arrangement. The only thing I don't like about this knife is that the backsprings are too tight. It's just tight enough to be annoying when I pull the knife out and try to use it for something. You really have to focus on what you are doing, there is no casual opening of this knife. But overall, I love it. I'm trying very hard not to order one of the new variants with the traditional blade arrangement.
#5) Tidioute #53 Cuban with "Dead Skunk" acrylic. Another real looker- this is a "purty knife". I am carrying this knife today, and I like it very much. I've never carried a knife with acrylic scales before, but the swirled red, black and white on this one are gorgeous, and seem tough enough to handle hard use. The whole knife has a very vintage vibe to it, it's unlike anything else I've come across. Very classy! The backsprings on the Cuban are much lighter than any of my other Great Easterns, the blades are quite easy to open. This is the only GEC I have that doesn't have half-stops. The blade profiles have great, slightly unusual lines. The only thing I don't like about the Cuban are the etches on the main blade. The HUGE "1 of 50" on the reverse side is a tad ostentatious, but will probably wear off. I'm slightly concerned that the handles may be too slippery, but I haven't had any problems yet.
Overall, I am very happy with all of my GECs. I have never come across their equal, and the prices are reasonable.
So, in my search for this, I have come across GEC and it's sub-brands.
