Pocket knife question

[SKL]

What is the best way to make a kid's pocket knife less stiff?

 

My kids have pocket knives that are difficult for them to shut on their own.  They are going to have a lesson on use of the knives at scouts this week.  I am wondering if there is anything I can do to make the knives easier for them to handle?

 

I bought the knives through the scouting organization, so I think they are the right kind ....

WD-40? Some proper knife oil?

I have no idea, and I'm not opposed to pocket knives, but this reminded me of my daughter's LA lesson today. She was supposed to write a sentence using the phrase "new pocket knife."  She wrote, "The little kitten hid the new pocket knife." When I laughed, she informed me seriously that she does NOT like knives. That's my little peacenik animal lover.  ;)

Oil and just repeated opening and closing.
