Hi guys,I have recently bought 2 used Spartans in a nice condition for like 10 bucks. I have a problem with 1 knife. It's main blade seems a little bit loose. As you know if you open main blade at the very end it "pops in" into extended position. In that case blade moves smoothly into its position and I can't feel and hear that popping sound. Can service repair that? I doubt I can do it alone. Thanks
I don't see any cracks, not even a small one. Could you double check that? If the spring is not visibly cracked, then the other things causing the problem could be:The corkscrew is worn out where it touches the spring,And/or the bit of the spring that the corkscrew touches is worn out. It explains the symptoms and you won't be able to fix it, but in this case I'd expect the corkscrew to be floppy when you open and close it.Or the spring has been deformed, pushed out too much by something. Which as far as I know could explain the symptoms, except that you would expect this to leave tool marks. Or it has a quality control problem(like with the heat treat), which as far as I know explains the symptoms.Or the pins are pinching liners on both sides of the blade too tight. If this is happening, then the can opener should not pop either. Maybe someone else can come up with more explanations.
