Back when I was a Teenager, I had a Valor "Eye of The Tiger," and I loved that knife. I don't know if it was stolen or lost, but damn I miss it.
I wore the pins out of it. One went, I fixed it, then the other broke and I fixed it the same way and I never had another problem with it.
My Father had died about 3 years before this, and he had alot of tools. Some of them were allowed to rust in the shed, the shed leaked, yet, I was not "allowed" to maintain them. Several tool boxes...
So...I just went out there one day when my mother was not home and started going through the tool boxes, picking up things to keep as she did not know what was in them ANYWAY...
I found some old pin punches...and there were several duplicates in there of various sizes...
On a hunch, I grabbed two of them and ran in the house, and one of them fit right in the hole of the Valor...but you had to push it a bit. Good fit.
I went back out to the shed and locked the pin punch in a vise and cut off a piece of suitable length, placed it in the hole, gave it a push...then I set it down on the back of the vise there was an anvil area, and I peened both ends of the pin.
Then, a couple/few weeks later, I had to do it again, after that.
No problem.
My advice is to find a pin punch where the punch part fits the hole or use a small drill bit shank that fits the hole.
I know you did not ask for "pin advice," but this would outlast the Jag.
