I put a Gator lock-back folding knife into my small kit (which is a good size pouch) and wear a LM Wave on my belt. The Gator is very light but quite strong for a Zytel+Craton handle construction. Might not be the world's best folder but served well and costs little. The Wave on the other hand is one of the best in its class. A huge selection of good size folders is available too (Benza, BM Pinnacle and axis locks, Spydy Endura and Native, etc.) so you can find your style.
If your kit allows the size of a fixed blade, even if it is a neck knife, that gives you the strongest/simplest (sometimes less expensive) blade option. This sector of the market is growing too. It can be skeletonized, without slabs, wrapped with paracord or left naked for less weight and less thickness. You still need a good sheath. Maybe one that you can also clip on your belt and still fits into your kit and cargo pocket. The skeletonized handle might have smart holes drilled for lanyard, holes for attaching paracord or improvised wooden slabs, and to attach knife at end of spear. The ArcLite is close to this concept IMO.
Hoodoo, nice set up. Have you tried to put the metal match into the pencil holder? Maybe with a rubberized thin cord attached to the carabiner so you do not lose it.
