First let me say my knowledge of Spyderco knives is limited at best. I have a basic knowledge of knife construction and do not even pretend to be anything but a novice. Now that I have duly humbled myself, let me inquire. Why does Spyderco use pins in their knife construction. I have owned many different brand production knives ranging from entry level to rather expensive ; Benchmade, Kershaw, Microtech, and a few other production knives. I have also owned a Strider SNG and a CRK Sabenza. None have ever used pins to secure their frames. Actually I thought, until I was educated on here, that pins were only used on cheap flea market knives. I know to the knowledgeable this might be a really novice question. Let me apologize in advance if I have broken any kind of etiquette in asking here on this forum. I will now sit back and wait to be educated.
