OK, have a 3.5" or so drop point hunter, about 1" wide at widest(Actually more than one, thinking I'll do several variations) similar to picture here:

(and yes, that's picture of nkfe by rlinger, and yes I asked him before I based a knife off of it). Probably shoudla asked about picture too, but didn't think of that. Will pull it if he asks.

Anyways, was looking for opinions on going with a full height flat grtind, or going only partially up the blade.

Almost forgot, ti's 1/8" O1, will be edge quenched and triple tempered.

Just thinking that a full height flat grind will make for a nice, thin, sharp edge.
 
Well, I wasn't going to say anything. But since you asked....:D

Starting out with 1/8" stock, I'd be inclined to forge the edge down to 1/16" or a little less and then just 'touch' it on the grinder to smooth out the surface. That would leave enough meat on the edge to keep decarb down to a minimum during heat treat and final grinding. I look at edge geometry maybe a little different than most folks. Doing a full flat grind on a 1" X 1/8" blade just gives me a case of the shivers. Of course, to be quite honest, I've never done much forging starting with 1/8" stock. The only thing I'd use something that thin for is san-mai or maybe a straight razor or even damascus. But that's just me. If these are going to be hunting knives they need a little more 'beef' in the spine in my opinion. And I'd be more likely to use 5160 or L6 since they're more forgiving in the flexible department. I'm just full of opinions this morning ain't I?;)
 
I would go with a full height flat grind, however, I prefer a thin blade for a user! Some guys like more "meat" on a blade, I'm just not one of them. That forged 0-1 would be an awesome blade it is one of my favorite steels. BTW, nice looking custom!
 
IMHO if the knife is used as a slicing instrument and not a hatchet or pry bar it will be fine. This might also just be my poinion cause I have a design that fits these specs. It can be seen here at the bottom of the page (Mark II)

Yes that blade geometry can be nasty sharp if the primary bevels are taken down to the edge with as small a micro bevel as you can get on there.
