Would the racing chopper have any advantage over the light chopper in a bushcraft setting?
The Racing Light Chopper is ground thinner and sharpened more acutely and is comparatively fragile.
I first heard the term "racing knife" from Dan Keffeler referring to the knives that cutters use in competition that they wouldn't let just anybody use because they're thin and tuned and work very well in a skilled person's hands but can be damaged if used carelessly.
When I was prototyping the Light Chopper there were three identical knives that Dan, Lorien and I all used. Lorien and I both managed to bend our primary bevels but (despite hitting much harder) Dan didn't have any problems. This is because his hits are straight and aligned without as much lateral force as the less skilled cutters.
The Racing Light Choppers are tuned for a skilled cutter and predictable materials. If you cut sloppy or hit a hard oak knot you could damage it. But if you're a skilled cutter and don't hit any rocks the RLC cuts like a lightsaber. I've been using one to trim my hedges, which is something I would not normally do with a knife, but it doesn't even require much arm movement and thin springy limbs come off like you're flicking a light switch. <--- you really can't do that very well with anything else.
If you're a reasonably skilled cutter you can get through 2X4s without any problem and it will improve your scores in the bendy straws, hanging ropes, cans and water bottles in a competition, or allow you to work more efficiently and with less effort around your house and farm etc.
I'd use an RLC in a bushcraft setting, but that's just me.
