Funny, but my 18-XRAY had some thick, grease like lubricant applied to the button area. Seems that the knife was sticky and re-set was nothing fantastic. Considering this, I re-lubricated the knife with G96 Sythetic Gun Lubricant and any stickyness has been allieviated. The knife is new and therefore somewhat in need of a break-in. But what's with that factory gel like grease? The knife now works like a charm with the G96 oil. AUTOKNIFE
