This is my grandfathers axe. Over the years it’s been re-handled 6 times and we’ve replaced the head twice. But it’s my grandfathers axe?
I have always liked this saying. Here is how I break it down. It was his at some point now it is mine. Handles are consumables so swap them out as you see fit. That is why they sell replacements. Now if he ever comes back and wants an AX I will give what ever I have for an AX to him or buy him a better ax.
Same goes for barrels. They are consumables so swap them or have them lined. I am sure your Grandfather would like you to use it and make your own memories with it instead of just looking at it and thinking of the old memories.
