One thing that surprised me as I tear into a near 70 year old Stihl Contra Lightning that has most of the exterior paint worn off and has been put to good use in its time is its felling dawgs. They have near all the deep red paint worn off and have had a huge service life but the points on them are like they were cut from the factory yesterday. They must have used high qulity steel on those spikes, I have seen nothing like it on any other saw. I think its overkill and not that necessary but its what you get on them ol saws, they were built with such craftsmanship.
