I think the Harseys are a great design. I have both a T1 and T2. Overall, I think the quality is a mark below Benchmade, but they are great designs, in terms of use and ergonomics. The T1 is a heavy use EDC for me. The T2 is newer to me, and I don't have much carry time. The fit and finish are good, but not perfect on either knife. I have tweaked both a little. The blades on the knives are great, however. They come sharp, and the S30V remains sharp. I would go G-10 or micarta. I don't like the nylon handles either. I will say that I have had very positive experiences with Lone Wolf Customer service.
I actually think the lock-up on both these knives is pretty solid. I would say that it is on of the strengths, and why I make the T1 a frequent EDC. The T2 feels great in the hand, and also has great action and a solid lock-up, but is a pocketful for EDC- it doesn't feel as comfortable in tighter jeans for me. But I do love handling the T2.
If I could change anything, it would be to take the blade away from a spear point and more of a flat grind.
