I bought a New Schrade 3OT, 5OT, and the giant 51OT. The 3OT and 5OT didn't impress me — the actions were rough, opening and closing, and the blade profile of the 5OT had a noticeable kink in the middle of the spine. Both of these were put in the Oblivion Bin, to be given away, discarded, or whatever
But the 51OT — that's a different story. I bought it because the prices of the made-in-USA ones had climbed out of reach on the big auction site, due to scarcity or trendiness or both. So it was New Schrade or Do Without.
Dang thing has a blade as big as a butter spreader! And truth to tell, it's really too big for any pocket carry. But everytime I see it, I start to laugh at the size of it. If I were into naming knives, I'd name it Muldoon. And it holds a pretty good edge, all in all. Bottom line? So far, it's been a good performer at a low, low price.
And yes, your mileage may vary.
