Patroit blade grind

Sidehill Gouger · Feb 23, 2015

As if chisel grinds weren't bad enough. I bought a Patriot maybe a month or so ago which I have EDCed around the homestead everyday since then. The handle fits my hand like a glove. Given the edge was beginning to fade I started to resharpen it. It was at that point that I noticed the company had used an asymmetrical grind on the cutting edge bevel like that used on some high end Japanese kitchen knives. What is the deal here? I bet not one in a hundred people know how to resharpen that type of edge if they even notice it in the first place. I don't care what the kitchen knife snobs say, I do not find it improves the cutting ability of the blade and it tends to make the knife favor either a right or left hand depending on the grind. How about just staying ambidextrous?

Every Emerson knife has a secondary on only one side

I like the Emerson production V grind (w/ the secondary bevel just on one side). For me, it handles just as any other traditional V grind (secondary bevel on both sides). Now the chisel grind, on the other hand, did feel like it favored one side or another when cutting some items. I would assume that as you use it more, you'd get a feel for it (and adjust as needed), and then it would feel natural.

As for sharpening, it'll take a pretty nice edge...

By "asymmetrical grind" do you mean the degree of the secondary bevel is different from front to back? I went to sharpen and that's how my Patriot is. It's also more than 30 degrees both front and back on the secondary, I can't go far enough out on my WE to get the right angle.. Why so extreme? I thought 20-25 degrees was best.

All the Emerson knives are sharpened that way, on one side only. There really is no secret to sharpening it, remove material from the side that it is already sharpened, raise a burr, and knock it off the other side. They definitely aren't for everyone, some people prefer other brands. Nothing wrong with that.

That's not what I meant Rev, I mean that the secondary bevel is at a lower angle towards the back of the blade, behind the belly of the recurve, than it is from he belly of the recurve to the tip. I noticed it when I ran it on my finishing stone, put a little marker on it to confirm and made sure it wasn't user error by putting marker on the edge again and setting a precise angle on my wicked edge. Both angles are at least 35 degrees plus, outside of the scope of the WE. I know they're chisel ground, I've had Emerson knives before, at least 5 since at least 2003. I meant two angles on one side and not the primary/secondary bevel, both angles on the secondary bevel, I thought that's what the OP was talking about?

- I've never had to use that extreme of an angle with the WE with any Emerson knife. I normally use a 23°-27° angle on the primary edge and a 15° angle for the other edge.

Good info guys, recently purchased my first Emerson (which happens to be a Patriot). Started looking at it and started scratching my head at how I was going to resharpen it when necessary. Tokerblue just solved my issue!!!
