4-H is like Girl Scouts kind of. Where they involve animals. Dogs, cats, horses, cows, pigs etc.
Usually they are the ones you see at fairs with their animals. With horses they get judged for a bunch of different stuff.
I spent a awful lot of time hanging around the fairs during those years.
Doesn't matter weather you get aerosol or liquid. For handles the liquid might be most convenient. I just wipe it on with a rag fairly heavily at first. Let it set awhile. Then just wipe it down once in a while to keep it nourished.
I sent Yangdu a couple cans after my first visit to wipe down handles when they arrive. Very dry down in Reno. Don't know if it helped. Also had her put a bucket of water in the storage area, hoping to add some moisture to the air. I see she still keeps the bucket there so maybe that helps.
Many here also take a knife when it arrives and dunk it in like a water bottle filled with mineral oil to really soak it.
For that it would probably be cheaper to just get mineral oil. Get it in the pharmacy section. Then just wipe it down with the ballistol or mineral oil from time to time and your good.
I also use the Ballistol on the blade on my users. Protects them and helps clean off pitch and chopping residue.
Take care of your khuk and it'll take care of you.
