I just realized that I posted a lot of "Boys Axe" pictures in Mike McCrea's "New Axe Project" thread, so let me summarize why I decided, after all this research, that a Boys Axe is the best single axe for my particular needs.
I started out wanting a packable-portagable canoe axe that could be used for light felling and chopping, limbing and firewood splitting while canoe camping. But I then changed my mind a little to give more weight to felling and chopping. That's because I suspect I'll begin to use this one-and-only axe on my 11 acres at home, which is exactly what happened to me when I got my first (of now three) tractors, chainsaw and machete.
I decided that an effective length of 24"-27" would be the best -- a so-called 3/4 axe, which are sometimes falsely listed at 28" before they are cut down during handle hanging.
I then decided on a head weight range of 1.75 lbs. to 2.3 lbs.
Within these length and head weight targets, I began my journey heavily favoring the Hudson Bay Axe (HBA) shape for aesthetic and historical reasons and also because it's convenient to get your hand high up behind the blade for fine carving tasks. For these summary purposes, I consider the "3/4 Scandinavian axes" from Gransfors Bruks, Wetterlings and Hultafors (Husqvarna) essentially to be modified HBA shapes.
I then traveled to stores to actually hold HBA axes with 2.0 lb. heads. They happened to be older Collins axes. I decided that these axes were a little too lightweight for the slightly enhanced chopping and felling capability I was after. I'm sure all of these ~2.0 lb. head HBA and Scandinavian axes would suit my needs just fine for canoe tripping, but I wanted just a little more chopping heft for home use.
I also became less enamored of the HBA head pattern, with its long beard and cutaway blade. There are lots of credible reports that these heads loosen easier than just about any other axe head pattern. I also decided that "hand carvability" with an axe was not a high priority for me with this tool. I now have three fixed blade knives for carving as well as several quality folders.
That led me to the Boys Axe, which I had been ignoring, but which has been used by the US Forest Service as their 3/4 axe for at least 100 years. It typically has a 2.25 lb. head. Many reports and videos show that these slightly heavier and slightly cheekier Boys Axes can fell and split more easily than the three lighter Scandinavian Axes. There are lots of inexpensive Boys Axes in hardware stores, mostly from China and Mexico if that matters to you. It does to me. I prefer Made in the USA.
All these learning experiences led me to the Council Tools Boys Axe, which comes in three increasing grades of steel, finish and price: standard grade, Forest Service grade head with Velvicut handle (only available from Omaha Knife, which will also sharpen them), and the full Velvicut grade. The Velvicuts all used to be a polished satin finish, but for the past six months have come with unpolished forge markings (but not with a black coating like the Scandinavian axes). The change in finish greatly disappoints my aesthetic preference, but doesn't affect axe function.
Here is the Council Forest Service edition in between a Husqvarna (Hultafors or Wetterlings) Forest Axe and a Gransfors Bruks Scandinavian Forest Axe. The head is clearly heavier and the Velvicut handle is slimmer than the Scaninavians, which can be seen better in a later photo below.
Yet, the CT Boys Axe (middle) has a fairly fine edge compared to the Wetterlings on the left and GB on the right. But it thickens up more than the GB near the eye to help splitting. (The CT FSS version has a plastic wedge in the eye, per FS specs.)
The CT Velvicut Boys Axe is sort of hollow ground from above the convex edge to the splitting swell.
It's convex along the blade from left to right so the center of the blade is thicker, which helps prevent sticking in wood.
The handle is thinner than the GB Scandinavian Forest Axe (on left).
Here is the sheath that comes with the CT Velvicut.
Again, I came to realize that I wanted a "compromise" axe for canoe tripping and light property clean-up. I don't want to buy and own multiple axes, which I suspect is the case for many of the advice givers here and, most very especially, on axe and bushcraft forums.
(I've just been on the phone with Zoro. They have a risk-free 30 day return policy, even if you use the tool, and they pay the return postage. Hmmmm . . . $98 for a Council Tool Velvicut Boys Axe, with an expiring 20% off coupon, for an axe with a $140 MSRP. Hmmmm . . . .)
