I have two natives that are simular but different. WHY?
1. Has the spider on the blade,a thumb print on the scales over the blade swivel pin and a 1 1/2 inch depression in the scales with the logo in it, wire belt clip, the blade is marked Seki city Japan and Y8-10 spyderco
2. No spyder on the blade, no thumb print or depression in the scales. Blade is marked Golden Colorado USA Earth and Spyderco cmps30V, the belt clip is the standard solid spring type clip.
I am not a collector, but a user and just wondering why the difference?
