Hi Kayaker2. Sorry to be gone for so long. sometimes my schedule is difficult.
No plans at this time for a kerambit. We've seen a few designs, but we're not sure if the market is there for a high quality production piece. The folding SPOT that we're playing with isn't a kerambit. The Liong design was also nice, and Bram also has a design.
It's really tough to try tpo make everything. Spyderco will generally introduce between 10 and 20 new designs per year.
Most companies are lucky to make 3 or 4 new designs. Much of what we do depends on capacity.
