Old as in the sense of made a long time ago, or something you have had for a long time? I don't have anything much over a decade old, in terms of how long I have had it, which is in regular use today, I had a lot of stuff stolen some years ago and what else I have has been replaced by more up to date kit.
In terms of venerable old tools however, I have a few of indeterminate age and probably considerable vintage. I don't have my grandfathers axe, but I have my great grandfathers gilpin hammer.
I don't know whether spectacles count, The frames I am wearing now, date from WW2, but you would hardly call them bushcraft kit, although I couldn't do a lot without them.
I do have a couple of other items from WW2 which I have had since the 60's, a leather ammo case for a vickers gun and a gas mask case, both of which have served for my cameras, or sarnies before now, but they were retired a long time ago, along with my dad's original bergan which fell apart eventually.
