Update: Spyderco service got back to me yesterday saying that they could only send me the clip screws (I had asked for the body screws too, since they are the same irregular size). They told me this was because the knife is not made in the US and parts are limited. They also told me that if I disassembled the knife I would void the warranty.
I'm sort of disappointed. First, saying that the knife was not made in the US and so they don't have body screws seems like a huge cop out. It's a spyderco, and covered under the same warranty. It also seems ridiculous that they said that if I disassembled the knife I would void the warranty. It's not like Spyderco sells any knives that are complicated to put back together; I've disassembled liner locks and lockback knives before for routine cleaning, lubing and such, and the inability to do so without voiding the warranty, in my mind, limits the functioning range of the product. Disappointing.
