The two main fixed blades are called the "Stavesacre" and the "Blackthorn" .... the stavesacre is the bigger
of the two, and comes with the cordura nylon drop sheath. It's also the one that is drawn in that schematic.
The blackthorn is the slightly shorter one with the drop tip and has the kydex sheath.

Both were designed as hard use, multi purpose outdoor knives. The blackthorn was also designed with
an influence toward a field utiltiy blade that would be good for skinning and game processing chores.
The stavesacre... being longer with a straighter tip profile, serves more of the tactical and self
defense role... as well as being a good allround general purpose blade. The schematic drawing
further explains the other features that both share in common.

Either one can be had in 1/8" or 1/4" thick materials. The thicker of the two is a good
choice for extreme durabilty and strength. The thinner obviously a good choice for weight savings, and
where slicing might be more important that breaking windows, spliiting wood, or hammering tent stakes in the field...

Both models are available with an abreviated handle, which adds the designation "SD" to the knife name.
This is a result of requests for a more concealable knife, where the longer handle might interfere with the
user's style of carring the knife.. but who still needs the general useabilty and strength of either design.
