I am not that sure any more about the quality of GB´s handles. The three I own since a couple of years are more or less good, which means:
the grain deviates a maximum of 45 degree from vertical,
the edge rests somewhere on its middle third when laid on a table lenghtwise with the butt rest on the table, too,
the edge is within +/- 5mm of the knob when loking straight along the handle.
But now I will not do mailorder with any GB!
Because this year we stocked GB in the outdoor shop where I work.
Of the ca. fifteen axes we got and sold, myself I would have bought less than five. The reason was the orientation of the grain and the amount of heartwood in the handle. The former was sometimes worse than stated above and with the latter, well, three out of four of our splitting axes had a handle with 50-100% heartwood.
A hunters axe was ordered by me with the shipment of our axes and I was lucky with it. Apart from a quite big gap between poll and handle its ok. For the difference in price between wholesale and retail I will happily fill the gap with the glue I use when making stick-tang knives.
Recently I started using Fiskars axes. Their prices are really good and the handles dont transmitt more shock than a GB. And with heavy re-working of the blade, making them much slimmer, they chop good, too. I dont know why Fiskars decided to fabricate normal axes with the head of a splitting axe, it doesnt make any sense.
I have only one Wetterlings, a LHA, the handle´s wood had a better orientation than the above mentioned GB´s, but was hung even worse. Still ok for the lower price.
Next week I visit a large outdoor shop in the next city, who usually stocks 10-20 GB´s. I will have a close look at all of them.
