Here's my small collection so far. I've thrown in two cheap hand axes just because they were handy.
A Comparison
I was asked to compare a Vietnam-style tomahawk with the Ontario SP16 SPAX, so I've done so here instead of making a totally new thread. The only Vietnam-style tomahawk I have is made by United Cutlery, so it's the one I'll be using. Note that the Vietnam tomahawk has had the following modifications done: edge reground, lanyard hole drilled and lanyard added; handle cord-wrapped; sheath cut wider to allow the wrapped handle; underside ground. The SPAX is as it comes from the factory.
Side by side...
The primary cutting edges. The SPAX has a flat ground edge, slightly under 4" long, and it has a slight curve. The Vietnam hawk has a 2-3/4" edge, flat ground. Note that the Vietnam hawk didn't come with the underside sharpened; I did that...
The SPAX' edge was good, but not great. View from the top...
The spikes. As you can see, the Vietnam tomahawk is ground on four sides into a cruciform spike; the SPAX is flat ground like a knife blade. The SPAX also terminates in an small "edge" whereas the Vietnam hawk is just a spike....
The SPAX spike, from the top...
The Vietnam tomahawk in hand...
The SPAX in hand...
The Vietnam tomahawk is void of any markings, whereas the SPAX is as follows. Left side...
Right side...
