I ordered and received a 3.5# Jersey a few weeks ago. I do not really have anything to compare it to, and am by no means an expert on axe design, sharpening, or use.
The factory edge is fairly thick and a bit rough. They describe it as a general purpose chopper so that make sense, I think. Also the grind did not appear to have perfect symmetry
I had a few days before I got the chance to go outside and use it so I had gone ahead and cleaned up the edge with a file and stones a little before ever chopping with it once. I do not believe I did a fantastic job with the edge this time.
The handle is untreated, and had a little splitting in the end. The grain was running the correct way. I smoothed it, rasped the bottom 8" for grip, then rubbed in a few tung oil coats.
One thing I noticed when laying the axe flat on my workbench (which is piece of counter top), it doesn't lay exactly the same way way on each side. There seems to be a little twist to the head/handle alignment, nothing I noticed in use though.
When the weekend came I chopped through a couple of sections of 12" - 14" dried oak. Here's where my inexperience gets in the way - it seemed to chop well, when I had a good, accurate swing chips flew. I did not always have a good swing.
That following week I worked on the edge some more, started with a file to sand paper on a mouse pad to a strop. I think I did a better job when I took it out the following couple of weekends, but I think my swing was improving too.
Bottom line to me, it is a serviceable tool for general use that needed a little work up front (which I enjoy). It is not a wood laser like I would expect a GB or Wetterlings to be, though that expectation may be unreasonable. No regrets on the purchase, I will probably get a few other tools from them this summer, but if I buy another axe it would probably be a smaller Wetterlings.
Hope this helps, I'll try to get a pic or 2 up later this week or weekend.
