I'm glad to see that I'm not the only one around here that hates this trend towards deep carry. I don't even like the wire clip, but I'll settle for one if I have to.
My philosophy is this: The point of having a pocket clip is so the knife is easily accessible. Not to hide the knife.
[I think you can have your cake and eat it, too, in this case. A deep pocket clip that, say, puts the top of the knife flush with top of your pocket is going to be above your keys and other pocket utilities because without clips they will sink to the bottom.]
When I reach for my knife, I don't want everything else in my pocket to come out with it.
[I certainly agree, and as mentioned above, I don't think having a deep pocket clip will cause this problem, at least it wouldn't in any pants I have, but shallow pockets and I can see could have a problem. The choice for me, wanting to conceal, is either no clip or a deep-carry clip because I am certainly familiar with having my knife get caught up with my keys, fall below my phone, etc.]
In my opinion, deep carry clips have no place on a larger folder. The only knives that need deeper carry are smaller knives that may not have the pocket retention due to a shorter handle.
[My waved Endura is the knife I most want a deep carry clip for. I'm not sure if you consider it a large folder (I do), but it's certainly annoying not using the clip and having it drop in my pocket and reorient to horizontal, which happens every time I have it in a pocket with small things (e.g., keys) instead of something bulky to block it (e.g., wallet, phone). For that reason if I had one choice of deep pocket clips for large knives or smaller ones, I'd chose larger; small ones aren't such a bother at the bottom of one's pocket. ]
Like others have said, I think the Military/Paramilitary has the best pocket clip placement of any knife. There's a good bit of knife above the pocket to get a good hold on, but still plenty of knife in the pocket that it's not going anywhere.
Who cares if someone notices you're carrying a knife. And honestly, how many non-knife people are gonna know that clip on your pocket is a knife?
[I'll get shit every block walking down the street with a knife visible. And call me a humanist, but I don't want to rely on the ignorance of people to know if the clip and part of the handle are a knife.]
STR does some fine work, even if I don't like low ride clips.
