What is off at the factory to cause this? It happens so often; I don't think the factory even knows.

I hear they only sharpen one side of the 4007 now, so they probably leave the cutting edge side longer so that when an edge is put on it it's closer to being symmetrical. Just an educated guess.

Personally it's not far enough off to bother me, but it might be irritating to you. If it's a problem just sharpen until it's even.

Is that a Kershaw Secret Agent boot knife? Because if it is, on the Kershaw website it says they are single-edge.

They must have changed at some point. My K Secret Agent is double-edged, but I bought it several years ago.

If the blades are still as thin as they used to be, and ground as fine as they used to be, then it shouldn't be difficult to sharpen the other edge.

I was wondering if the fixture was off in the factory or when they flip the blade over; the modified edge throws off the angle for the other side. If it was setup right; it could never happen.

I wasn't referring to the sharpened edge. The center line down the side of the knife. On the CS Counter Tac 1, it's centered. The Kershaw Secret Agent is way off center. I have seen this before with other knives.

In your first picture it actually looks worse at the ricasso, it's just more obvious at the tip.
I wouldn't buy it or keep it.

Pretty sure this is the reason, I've seen it on a few other knives. Typically, it would look ok on one side and like OP's pic on the other, because the bevels weren't even.

OP, what does the other side look like?

The top pic is one side and the next pic is the other side.

The center line veers off to the side.

Pretty easy to miss grind an edge only have to be off a few thousands on a set up or have some slop in cnc.

$30 knife, can't be to picky... Or it will cost twice as much.

It's a small stabby dagger . It will still "keel" ! :rolleyes:

But if it offends you , I'd return it for refund and get a Cold Steel Drop Forged Boot Knife .

Much stronger , tougher , better knife and maybe even symmetrical primary grind .

I never understood the purpose of a single edged dagger . You sacrifice slicing power for that DE , but then chicken out ? o_O:thumbsdown::thumbsdown:

I don't mind it as it's still functional. I just wish they'd correct it at the factory.

Mass produced knives done by a worker getting paid peanuts. I doubt they worry if it's exactly centred just trying to get as many done as possible.

I know this is apples to oranges. But in this old video, watch it at double speed so it plays quicker; notice no humans touch the product and there are some grinding operations done. I just thought the initial large grind to give the blade it's contour was done in a jig or a fixture so it couldn't move.

A symmetrical dagger is probably the hardest blade shape to grind.
