I had posted the Boker Arbolito 'El Gigante' as being my personal pick for an underrated knife.
I had to think hard on what I personally believe to be a overrated knife.
My personal choice is actually a brand, and it has already been mentioned during this thread. It, the brand of knife, is GEC, (Great Eastern Cutlery). I only have three specimens, one is a fixed blade, the other two are traditional slipjoints.
I only have three for a reason, and that's simply because I didn't feel I wanted to add any more after getting those three. They're nice knives, two being less so than the other one. I simply didn't feel they met the hype. Nor did I feel they were worth the money I had paid for them.
Of the ones that I have, my favorite, and best made out of the three, is my Tidioute 'French Kate' in Ebony wood, (a lady leg knife). What's weird about that is, it seems that the majority of GEC enthusiasts didn't care for that pattern, it being too gimmicky for most of them. Obviously it's supposed to have some novelty factor to it. I mean, just like the original lady leg knives of the past, it certainly is a novelty, but it's also a functional cutting slipjoint.
Anyhow, I'm not saying that GEC is a bad maker of knives, they can, and do, make nice knives. But... I really do feel that they are highly overrated, (and overpriced).
Obviously, the overrated and underrated thing is going to likely be more opinion than anything else, so this is just that... my opinion.
