Is this normal for a knife blade?

Thats one of many reasons i dont buy anymore bokers that are made in china. just abismol quality.

boker should replace that without issues tho.
 
Definitely needs to be replaced by Boker. I wonder how that happened, maybe punch blanking the curved slot?
 
I wouldn't worry too much about that. It's in a non structural area and doesn't look to pose any threat to integrity. It's an "artifact" from the manufacturing process, these types of things are normally seen with cast parts, but it can happen with parts that are stamped out too.
 
I don't know but good luck getting all those itsy, wittsy, teeny, weeny ball bearing back in place. You / he are braver men than I Gungadin.

When I took my Urban Trapper apart I stopped short of taking the blade out. Pretty glad I did.

I must say I agree with dwdickey. That ragged area from the die cut is the least of your worries. The critical areas are those skinny little areas of steel at the ends of curved cut out. When I first saw how little metal is holding that relatively long blade I did a triple take. Don't go levering your car door open with it or anything.

My rehandled Urban Trapper is right up there with my top five knives of all time but I use it with a puckered danger gauge. I hope Ol' Brad Zinker had it all calcumallated right.

My kwaiken is smooth and clean. Nothing like that.

Wowbagger, it's easy if you do it inside a ziplock and put them back with a dab of grease on a needle.

Yah I could do it . . . buuuuuuuut . . .

Thanks for the tip !
Kind of like handling fuel rods in a Nuke plant (without the telecherics) . . . nothing to it.

Shades of The Andromeda Strain. :)
 
Looks like it was stamped out, you see it on the spine of most moras too, a result of pushing a piston trough metal.
I don't think its a flaw, just a matter of how well the knife finish is.
 
Thats a defect in the metal for sure. Try to exchange it for another one.

That's what it looks like to me too. You can see that the areas where the stop pin makes contact on either end of the slot have been finished/polished, but the weird looking area just passes by the stop pin as the blade is opened or closed. As long as the action of the knife isn't rough due to that area, I wouldn't sweat it either. Regardless, if it's going to bug him, I'm pretty sure Boker USA would be willing to swap it out for another one.

edit: For comparison, here's an unfinished Mora spine (borrowed here from bfc), and this one isn't as bad as a couple I've received, but they still work just fine.

They probably stamp the blade blanks and leave machine stock (extra material) in the stop pin channel. They secondary machine the channel for the stop pin and there was probably some misalignment due to poor fixturing or a sloppy machine operator and the machine stock was not cleaned up.
