I have GEC #23's both a single blade and a double. Both Fantastic! I have not had to fix anything on my GEC knives yet.
(large and small pioneer #23, and Scout #73. these are GEC made)
Gec also makes a elephant toe, (some all steel liners and bolster). I have one. It is a great knife, and beefy, though still cuts great!
(the #23 is not in this pic, that is a #73 next to the sunfish)
Single blade #23 Northfield Yellow Rose (this was the one that drew me back in to traditionals. Gifted to me by Flymon)
Single blade versions of the elephant toe are available as well. Mine is the two blade version, with single spring.
I have a Queen grandaddy barlow (a Queen/Burke collab). It came with a gaps, and wiggle, but a real strong spring. I fixed the wobble. And re-profiled the edge to cut, instead of tear. I carry it often.
I have an S&M grandad barlow. Thinner blades, and better grind at the edge. Blade wobble, and gappy. I fixed that, and carry it all the time. One of my favorites. I bought one for my dad, with no gaps, or wiggle.
I really like the steel on the S&M file and wire (Ats 34). I also love the edge holding on the Queen (D2).
The D2 queens I have received (only a sample of 2), have thicker grinds, especially at the edge, than I like.
If they could thin those babies down from the factory, and deliver them without gaps, they would be impossible to pass up.
The GEC have been my favorite for finish, and pull, and grind.
Queen has a lot I like the patterns of (they are significantly less $ than the GEC).
