I put the Hudson Bay axe to work today with an old Collins axe from my grandpa. The Collins was fitted with the same handle as the Hudson Bay which is similar to the length of the original handle on it. I cut down two small trees with them in side by side comparisons. The last one was a 4" cedar which I then cut into lengths--alternating between the two axes.
Initially I thought the large bit of the Hudson Bay would lessen penetration. However, on a 4" tree I could see no disadvantage to the wide bit (4 1/4"). I don't know how it would be on a larger tree, though I don't think I would use an 18" axe on a much larger tree, unless by pure necessity.
IMO the Hudson Bay cut better than the traditional Dayton style Collins. This was especially noticeable when using an oblique angle swing. The long thinned bit of the Bay axe really dug in and was not as prone to glancing. The head is a bit heavier than the Collins and certainly more bit heavy. There was no tendency for the poll to roll on a hard angle cut, helped probably by the bit heavy balance of the head.
I choked up on the handle of the Bay axe to shave off twigs and skin the bark. The long wide bit is definitely an advantage for this. This particular Hudson Bay style head seems like a mix between the standard Gransfors Bruks SFA and the Bruks carpenter axe--a compromise design. Perhaps this is why the voyageurs liked this head because of its versatility. I was a bit skeptical at first with such a wide bit that was so front heavy, but now I can see the value of the design, if the small axe is used as a do-it-all type of tool. Obviously this is why the tomahawk style was so popular among the frontiersman who regularly depended on it for a variety of chores.
The steel is also of decent quality (will have to use it longer to know better) as it did not lose any of its edge after the use, not even needing a stropping to bring it back to its original keeness (granted that I did not use for a couple hours at a time yet), which on lesser quality steel does not take real long to lose the keeness of a fresh stropping.
Since it seems as though there is little experience here with the Hudson Bay axes from Council Tool Company, I'll say that from what I have seen to date, I could recommend them as a decent trail/camp axe.
