Wow, this is controversial.
Although I am fine with regular ol spyderco clips and have never desired deep carry, I certainly understand the demand for deep carry clips.
I do respect spyderco for not squashing the small businesses manufacturing these clips.
What I don't understand is how passionately some people oppose those who express desire for something. The "shipping of internal parts" thread is the same way. People ask Spyderco for stuff all the time. Many of these things I do not care for and would never consider buying, but I don't post in the thread asserting that spyderco shouldn't humor their suggestion, nor do I criticize the suggestion at all. I leave that to Sal and the spyderco staff. Doing so keeps things much more civil. The existence of products that I dislike has never and will never bother me in any way, and neither does seeing someone request these products.
Unfortunately, whatever happens, happens. Spyderco is very friendly and open to some suggestions (different models, sprints with different steels/locks, etc), and not so open to others (shipping parts, warranty related suggestions, deep carry clips, etc). At the end of the day we're all still here because we still love and appreciate spyderco. I truly hope those who wish to see this idea come to fruition find a solution. Let's just be kind to one another!
