Now I am thinking of using Vegetable oil in a Water Pik to clean some of my knives. I think that it would be a mess

Here are my Questions.
1. Will the water pik work with Vegetable oil? Or will it mess up the seals and the pump?
2. Will the oil hurt any thing in the knife by using presser to wash it?
3. Will the oil hurt the ink on Schrade Scrimshaw?
4. Will the oil hurt CELLULOID handles?
5. Will the oil hurt Leather handles?
6. Has any one tried such a dumb thing as this pressure washing?
IF so PLEASE tell us.
