My first was a small Tinker model that had the square shank screwdriver/file combo, I found it my dads old tackle box where it had been used to trim line and gut fish for years. I still have it and its in just as rough shape as it was when I found it, blade all scratched up, handle scales loose and falling off, and little to no snap in the tools, but I will keep it as is for memories sake.
I have cleaned it properly many times and the snap is still all but gone, its the only Vic I have ever seen with so little snap, it was abused heavily by my father or maybe the guy he got it from so I think it is just worn out. I don't carry it so it doesn't bother me in the least.You might be able to wash it up in warm water with a little dish soap, let it dry and give it some lube. I've had some success improving the action of SAK's doing this. There are replacement scales available also. I know it changes the mojo.
