I see a hole in a blade I automatically think Spyderco, before I recognize it isn't one (if it isn't). And if it isn't, my next thought is 'they copied Spydercos idea'.
In my 4 years as a budding folding knife enthusiast that has become my automatic thought process. So to me that's a real Trademark, regardless of the correct definition of the term.
To me, the Spyderco hole isn't really worth arguing about, it's simply iconic and alluring, within the context of the company as a whole.
I've gained a real feeling of respect for Spyderco and Sal Glesser, in no small part from what I have gained from reading through Blade Forums since 2012.
The way Sal just posts here along with the rest of us seems to be a unique thing to me. Not that long ago I posted pics of a Para2 I had custom scales on, and Sal Glesser posted in the thread "Hey, thats a beautiful mod".
I mean, I had done something that voided the warranty, had changed it from how he designed and made it, and he was positive about it, on top of the fact that he posted just like any of us ordinary mortals might do.
I still smile to myself about that.
Spyderco to me has a face, a personality, a character, that I just don't see in other makers.
Spyderco's dominate my collection, and will continue to do so.
As I understand it, the Para2 was the result of Spyderco listening to, and responding to, customers feedback on the original Paramilitary, which had a 3" blade. This happened several years ago.
More recently I recall reading on BF about Para2's modified to 3" blade length and discussions about it, including comments from Sal. Some time later I hear there will be a 3" Para3 coming. The community expressed what they wanted and Spyderco is responding. Again.
Yes Spyderco is in business to make money, of course they are. But I can't help admiring the way the do it.
I have, and really like, some Benchmades, and their customer service is great, but BM left me cold with the enforced MAP thing. They just became too expensive for the sake of wanting to 'appear' a cut above other production knives. Benchmade seems by comparison to be a faceless company, more interested in a 'business model' than their customers feedback. I may still buy a BM if I like it enough, but that will be very rare.
