North Man - The awl is not on the G&E tool. It doesn't look familiar, but I'll keep an eye out for it as I mess with the collection.
GigaHz - Mine has the two different scales, standard and evo.
Syph - My understanding is the knives were made in small batches. The early ones differ substantially from the latter ones in their tools, as mentioned above. There also appear to be a number of smaller variations between batches, based on looking at a number of photos (quick way to go blind). This is one area where collecting variants is probably out.
Mine doesn't have a date or serial number on it that I can see.
I've never completely closed up mine. It's a bit like handling a porcupine.
