You waste quite a bit of wood when you use an axe to fell and chop trees into lengths. I know it's wonderfully good exercise and does not invoke engine noise, machine maintenance and fossil fuel odours but it is also very (very) slow going.
Manual bucking and felling saws make clean cuts, are fast, efficient, waste very little wood and have been around for 120+ years! As a consequence axes have been relegated to limbing and splitting already a long time ago.
I was lucky (?) 45 years ago to have experienced the very tail end of an era where gov't workers were required to use axes to chop down entire forests. This was entirely for the purpose of land clearing so waste was not a concern and older chainsaws of the time with direct drive (no clutch), no safety features and no vibration damping, were still common and very dangerous to use.
Borrow a few different types and weights of axes and give them a real good workout before committing to buy!
Looking at the pictures you provide, myself would be a sucker for getting the Jersey only because of the generous wood contact in the eye and the no frills haft. But then again that's just me!
