I got the vulcanized fiber from one of the better known knife maker suppliers. I know you should not leave a knife in water, but my wife doesn't understand that. I made a paring knife as one of my first trials to learn. I used a white liner next to the blade to set off a vine pattern file work with emerald green dymond wood as the handle material. The knife turned out very well. The white fiber liner not only swelled it also has discolored. So I am trying to find out what I can use for a white liner on a kitchen knife. I used straight 1/8" stainless pins glued in. The swelling of the liner has caused the pins to come loose. If I find a good liner material I will replace it and use corby bolts instead of pins.
Thanks,
Mike
