I gave a friend of mine an Opinel #10 (maybe 4" blade) to use at his fruit and vegetable stand. He commonly gives customers samples of his products, mostly fruit, and needed something he could pull out of his pocket, pick up a nice piece of fruit, and cut a wedge for the customer. This worked really well until lately. The collar is metal to metal so I don't think this problem is related to swelling wood, tho' it might be the case. Obviously the fruit juice and other stuff will run down into the top of the knife, no matter how often one wipes the blade (and sometimes, this is not an option. I help him out part time and sometimes you're so busy that proper maintanance is not as often as one would like).
The collar has gotten to the point that it will not turn to lock the blade open or shut. I used a screwdriver to twist the collar in both directions ten or more times and it doesn't seem to loosen at all.
Any suggestions as to what might be the cause, and recommendations for remedies. Bear in mind that this knife is cutting food products for customers, so regular oil would not be appropriate. I also think that using vegetable oil would end up with some spoiled/rank stuff in the areas that need cleaning. Help, please!!!
