I dunno guys...
Thinking of this as a true survival knife, it looks like that one could be a winner. I don't like carbon for a knife that could actually be used in a survival situation of for use in skinning or preparing game. Or for use in any wet (rain/mud/food prep) conditions. Rust prevention is an unnecessary nuisance when there are good stainless steels out there. 440C at that hardness should be great. Note included is a Lansky sharpener, so if you can keep your kit together you shouldn't have to worry about field sharpening.
The 3/16" looks like it would make a pretty sturdy blade, and could certainly be used for some light batoning to get that dry center for tinder out of medium sized piece of wood. It could also be used as a blade to hit to chop through larger materials by whacking the spine.
I think far as the thickness to slicing ratio would be, I don't believe it would be that bad at all since it appears to be ground back about 1/2" from the edge of the blade. That should do it.
I like the slot head screws. Remember, this is to be an emergency, "go to" tool when needed. I don't think I would want to be concerned about having the correct wrench or key to get into the handle when I know I could have had handle screws that could be removed with a nail, a bent piece of steel, or something found along the road. As far as them wearing out, remember.... emergency tools aren't EDCs. Get another set if you are worried about head wear. How many times would you be in that handle for normal use? And for normal use, wouldn't you have access to a slot head screwdriver?
+1 on the small recurve as the little curves do make the knife have a bit more cutting power without making them harder to sharpen.
I really like the sheath, too. It's a nice one and I like the security of the removable fold over flap. Probably $65 retail in the sheath. Micarta handles, fire bow divot, storage in the handle, wire break notch, glass breaker butt and lanyard hole... not much left out!
Then you get this with the knife as well (I realize these items have little or no value to those here as they already have their favorite versions of this type of gear):
Includes Free: *Survival Saw *Lansky Sharpener *2 Ranger Bands *Compass *Fishing Line *2 Fishing Hooks *Offset Screwdriver *P-38 *Snare Wire *L.E.D. Light *Sail Needle
*Fire Starter *Razer Blade *Snap Link *2 Safety Pins
This is actually the first TOPS product I have seen in a long time that looks interesting.
I hope someone let us know if they get this one!
