What’s this? a TF quality control question.

So I recently got this knife on BST and it didn’t jive with me, a catch and release. went to take more photos and I just noticed this. Just want to see if you guys can diagnose that this is not delam and it’s safe to pass on. If it is delam, I will pull it. Apologies ahead of time, not tying to advertise here just trying to be as transparent as possible.

Are you talking about the slightly counter-sunk core steel along the spine? If yes, it's 'normal'. I've seen it a few times on these older prelaminated Western Nashiji blades. GLWS

Can’t tell for sure unless you grind it down a bit to see if it ends shallow.

Possible corrosion also, the core & cladding corrodes at different rate, like slow etching.

Also being lower its harder to keep dry, hence the rust spots.

So it’s safe then. Nothing to worry about just classic TF you’re saying

Every tf nashiji I’ve seen has the core exposed down the middle like that.

Exposed yes, recessed no

Normal for TF nashiji. I've seen that sort of "recessed enough to catch a finger nail" spine on multiple nashijis over the years (in other words, not just from one batch). There's a thread or two on here or somewhere else about it.

Hard to tell from pics, but in the second photo there is a spot along the spine that I'm guessing is about 3" from the tip that looks like more than just recessed core steel.

Ah yes now I can see it on my laptop.
