That thing'll take a beating, so don't be gentle with it.
As for next moves... consider an HI blade that is fullered, just fer a change. Really adds to the aesthetic and the functionality. Try a Gelbu Special, Chitlangi, Hanuman, HI AK Bowie, Berk Special. The Berk Special and the Fox's Folly models have big blades and multiple fullers. YCS is outta production, but we see a few come through every now and again.
Beware, I've seen a few "plain" YCSs and AK Bowies, meaning they didn't have all the normal fittings or fullers. Still good knives, just not as fancy.
If ya want real workhorse, get one of the villager models, they're the beaters of the khuk world, and are darn near indestructible. Also make great project knives, as they are what we western folk would call roughs, or partially finished (ie, unpolished handles, brush finished blades).
Enjoy!
