I have some Osage log splits that are about 5 years old and bark on. I think that they are over 6 feet long. Not ideal but I think there are some bows in there. I sprayed them with bug spray to keep the wood bees off of them but they probably have "some" damage. I split all that I will ever use out of them when I got them. If you are in the Tulsa area and you want them, let me know.
