One day someone on here is gonna have at his disposal an original lathe/turner for classic curved axe handles. And will generously offer to run whatever wood is sent to him/her over it. It would be a truly enlightening experience to be able to haft a bunch of identical heads (gotta be able to get some version of these, by the dozen, from Mexico/India/China) with all different types of wood and get people's opinion (and their experience) with them.
I have long been a sucker for canvas-cover cedar-strip canoes of yore. "Chestnuts" from Fredericton NB especially. Lots of armchair and collector folks out there appreciate that there is visible craftsmanship and history behind any of the old woodies but physically being able to experience the unique flex of one when determinedly paddling (compared to that of a modern fiberglass/Royalex/aluminum/Kevlar factory boat) is not widely known.
I would really enjoy being able to compare an Ironwood haft, Ash, Hickory, Beech, Locust, Maple, Elm etc. when it comes to comfort and durability.
