I don't think anybody mentioned it, but please correct me if I am wrong...doesn't the SOD LE have a sort of collector value? I mean different grind, no coating, and serial numbered. I was under the impression that they were more of a collector piece? Sure it is an extreme use blade, but I get the vibe that it is more of a show piece than a user. My take is that the CG is the user, and the LE is the safequeen.
Generally speaking, the relative rarity of the blade in circulation is what makes it a collectors item. The serial number just ranks the desirability some. Obviously there's only one #1 but I doubt you would find that #33 is more valuable than #42 knife condition being equal.
We don't know how many SOD LEs were made so it's hard to judge their collectable status right now other than among those who ordered them and know they are darn good Scrapyard knives. Because they were "build to order" it may be that there will be more SODLEs in the market than Ganza releases where the numbers might be relatively small. The fact is we don't know, one way or another. However, I would guess that some of the older SYKCO blades (S6, SS4, DFs) will remain somewhat rarer just because older knives take on a life of their own after a few years and many disappear from circulation.
