How the hell can a guy have an opinion on knives he has never owned ?
. . . oh . . . that's easy.
First I will attempt to add what has not already been mentioned.
Second I will try to be positive and not troll. That's not so hard; these are certainly iconic knives and people enjoy Emersons.
Now to my arm chair observations :
First off . . . the chisel grind this CAN make a negative difference or not matter depending on what you are trying to cut.
For instance I have to cut rubber hose (softer = more difficult to cut) soft and up around an inch and a half OD. The end has to be square with crisp edges. If there is any wave or ragged edge I have to take it to a power grinder and square and clean it up. A single bevel (chisel grind) with the flat on the left (I'm right handed) would make the job go better. See Japanese Chef knives. THE OPOSIT IS TRUE. Guess where the bevel is on the Emerson ? So for slicing square for a right hander the single bevel (chisel) grind is a sinister foe.
Next the slotted screw head for the main pivot. I have changed my mind on this one. When I first saw it and even to this day that "old time" slot screams cheep crap / artless cost cutting.
BUT I have finally come to appreciate that one can turn that screw with about anything from a washer or chunk of scrap metal to the most common screw driver. It is what is in many of my Apple wireless products that take rechargeable batteries such as my key board and track pad. All I have to do is use a penny or nickel to unscrew the battery chamber cover. SO THE SLOTTED SCREWS ARE HIGHLY PRACTICAL. Though I'm still a Torx guy all the way and when I don't have a set of Torx near me I am in serious do do and probably won't be worrying about my knife pivot.
The knife, with the reverse bevel egros for a right handed person, is good for cutting through thick rope with a hammer when you don't care about the shape of the end. I'm being serious the edge is straight like a sailor's marlin spike knife. Good for all manner of high energy demolition. Good for shaving curls off stuff; the edge shape kind of lends it's self to that. If you like Tanto blades then by all means this is your knife.
Good if you need a knife that will open super easy one handed even if your thumb is torn up (the wave).
This is an interesting thread and I am learning more than I can contribute. I might one day own an Emerson so I'm learning.
PS:
The 7 has a neutral, accommodating handle; the Horseman encourages a more specific grip.
I'm all about handles that are more neutral and plain. Think Cold Steel Ti Lite or Sod Buster RATHER THAN Spyderco Manix.
