j b weld.

Please don't take this the wrong way but I think it's a genuine Katrinka's or Wenger SAK. I'm a member of the SOSAK forum and I've never seen a genuine SAK with both a corkscrew and a Phillips screwdriver on the back tools.

The the rivets are another point, on a Vitorinox or Wenger they are made of brass rods with brass collars at both ends, so unless it's a custom made or mod'd SAK I would have to say that its not the genuine article.

The only way to make sure is to look at the tang at the base of the main blade when its open.

I had never heard about Katrinka knives, I checked the web but couldn't find anything. I am something of a collector (rather a gatherer with no plan)and I would like to take a look at them.

whoops, typo, should read victorinox.
guess I should prof read more

I agree it doesn't look like a Vic. (You can get replacement scales for those and they just pop on without glue.) I've glued my beater Vic a couple times. JB Weld was a wreck. I probably wouldn't try Gorilla glue. Superglue is too fragile. Contact cement (Duco) is the winner so far. It's slightly flexible, not runny, and doesn't expand as it cures.
