I found a nice condition used Infidel at a gunshow several years ago for a great price, and I couldn't resist, especially when the wife said I should get it (she bought me my first Benchmade, a 3550). It was legal to possess but not to carry at the time in TN. Since then, the law changed making it legal to carry, but I don't, and probably won't, ever carry it regularly.
If I hadn't gotten such a good deal on it, it wouldn't have been a knife I would have ever considered buying, so it's kind of a trophy knife for me. It's just too nice (and expensive) to carry and scuff up, so I keep it around to display and show off.
Benchmade makes quality knives, and the Infidel is no exception, plus it has the cachet of being an OTF knife, which always wows people not familiar with it. The play in the blade is negligible, but there is a tiny bit of play as compared to a good folder. The play hasn't grown any over the years of cycling the blade, but it's seen no actual real-world usage, either.
I've been eyeing those, as I like the aesthetics and very low riding clip.
I haven't been able to handle one though, can you describe the feel of opening/closing? How much pressure on switch in either direction, how much play in blade when open, etc. I have only handled cheap autos.
I think having a knife for enjoyment is plenty of good reason! But I can carry one here, in most places with my ccw, so I want one useable as my left side backup if needed. Also to show off when needed.
Like all Benchmades, the Infidel is made to close tolerances with quality materials so blade play is minimal. Just guessing, I'd say it takes 5-7 lbs. of force to open or close it, and it has the same smooth action in either direction.
It clips deeply into a front pocket, stays out out sight, and feels comfortable to carry, but it does weigh 5 oz. which is only two ounces less than a loaded NAA mini-mag.
I don't recommend spending that kind of money for one without handling it personally first. One of the deciding factors in my purchase was that I was able to try it out before I bought it. I was impressed, but new Infidel money will buy a nice carry gun, and even at the used price I paid, the NAA with both cylinders was less expensive. Together, the NAA and 3550 cost less than a new Infidel.
