Kabarcamper,
We stopped 1247 production because the blade shape caused all sorts of problems at the factory. The short, wide blade had a tendency to warp (cup as opposed to bend) and as a result, the grinds were hard to keep even and symetrical.
Since we also wanted to redesign the knife to add things that the customers wanted, we decided to discontinue and then reintroduce the newer version (1278).
I agree with you; the old warthog, even with some issues, was a great, practical knife. We still get a lot of calls from people who want them.
Hope this helps.
Best Regards,
Paul Tsujimoto
