Kelly dynamic

i dont know, maybe hardened poll because kelly dynamics are hammers, i dont know what a dynamic perfect's differences are
 
They did have two grades of axes. I believe that the Dynamic was a first quality stamp. I base that on the other tools that share the name(hammers).
 
There was a line of hammers below the Dynamic. They were not as well finished and didn't have as nice of handles.
The Dynamic hatchet is a little unique and the hang is closed on both ends. They also had a handle change and the flat sided one is a better fit for large hands.
 
Relevant and illustrative shot of hammers and half hatchets from 1954 rjdankert. Thank you very much. Goes to show that manufacturers' strive for novel or fashion designs was already underway in the 50s. Old timers would have stuck by the Perfects and apprentices and first time buyers might have been tempted by the new-fangled Dynamics.
 
The Dynamic is a great line by my experience. I think it's similar to a Flint Edge in quality - in other words in all functional matters as good as a Perfect but maybe with a slightly lower degree of finish in the finest details.

Here's a Dynamic hammer I own. Note that it is also a Flint Edge. I rate this hammer as equivalent to my 16oz. Vaughan straight claw rip/finish hammer. Totally top shelf. The only real flaw is some grind marks on the side of the bell. Those mean absolutely nothing to function.

It amazes me that 7 and 16 oz heads were 'the' hammer heads of the day. I've been at this for 50 years and still consider the carpentry classic 16 oz Stanley wood handled claw hammer to be a toy. My first (1972) and most used hammer is a 20 oz framing, still.

Your right about that.
That closed hang makes it limited in versitlity. And square faces are fine in some cases but are bad anywhere a hammer mark may be noticeable. The Perfect half hatchet is just going to work better for lots of things.
Still for reasons I probably don't fully understand I like a closed hang on a hatchet when practical and I use and enjoy that pattern.

Interesting that hammer also has a flat sided handle. I think they are earlier and later went to rounded.
