As would be expected of a knife from Tashi and Reate, the design, fit/finish are excellent. It is a beautiful, well-made knife with a good edge out of the box. But as some others have mentioned, the flipping action is beyond difficult. This is not a matter of breaking in, it is just far too tight, and is almost impossible to open with one hand. I have a couple of the Kirby Lambert's from Reate, and they did not have this problem, they were ready to go out of the box. Unfortunately, the quality control on this heat seeker is lacking and there is no way this knife should have left the factory in this condition. Either the flipping tab should be slightly more prominent to provide greater leverage, or the action should be looser; both would probably be advisable. Also, the edges on the flipper are far too sharp.
On an unrelated note, the shipping process from start to finish was total crap, with misinformation at every step from Drop. Ultimately it took three weeks for the knife to be delivered by the time it was supposedly shipped. Initially I was told it was coming from New Jersey, but it actually came from China via the Netherlands. Drop needs to do a better job on shipping and communicating with customers, especially with shipments that are international.
*Update: Spent about an hour doing a bit of filing on the flipper tab to smooth out the sharp edges which helped a little. Also removed the pivot screw on the carbon fiber side to add a little lubricant. It is still a nightmare to open via the index finger as the detent is ridiculously strong, though changing the grip and using the thumb makes opening with one hand more manageable. As the remediation was not successful, I'm knocking it down to one star because a knife that you cannot or will not use, is not much good, regardless of how beautiful it is.
It really pains me to give this knife one star as I very much wanted to like it, (the combination of carbon fiber and titanium is SO beautiful), but I would not recommend it, particularly given it was $300; what a shame.
