I generally do not post, being relatively new, I just read & learn. I have +/- 600 knives. Collected over many years. My question, how can I replace a spring without spending a fortune. Is there a good old boy trick ? Is there a jig I can buy without breaking the bank ? Are there directions I can access. I would like to get into repairing my own knives. Can anyone help a poor Old man ? Thanks Frankb
