I don't know about cold steel's HT of CPM-3V but others in the same are highly regarded.
CPM-3V is tough steel that resists rust about as well as D2, has very good wear-resistance relative to its carbide load, is "better" steel for your intended use though it may not be as easy to sharpen as O1 or O2 depending on your equipment.
As a dedicated wood cutter, you may not find the handle as comfortable with it's straight-shape, but the rubber/kraton will help make up for that and be warmer to use in cold weather. I'm not sure how thick the edge is on the Master Hunter, that will determine how well it penetrates for carving, but it shouldn't be too hard to adjust if it isn't to your liking. The sheath is designed to be more weather-proof and adaptable to various modes of carry, AND it will fit my
Universal Kydex Sheath Extension if you are interested in even MORE versatility
HOWEVER, the Master Hunter is much more "tactical" in appearance than the classic design of the other knives you were considering. If you are open to going that route, MANY companies offer models with similar designs. It's also made in Taiwan, if that matters to you.
Is the CPM-3V Master Hunter worth the extra $$$ over those others? *shrug* I personally prefer the design of the Casstrom handles but the blade of the Master Hunter - I don't much care for the "scandi" grind and I've never had a problem carving with my FFG blades, and CPM-3V lends an aura of quality and dependability (durability) that may make it worth the extra money. If those preferences don't apply to you, get whichever you like the look of most :thumbup:
