Ok, so I finally got out and beat the Mistress a bit. It's a pretty amazing knife.
Here's a +/- 7 inch hard, well seasoned Maple. Using a very unskilled and inefficient technique this took under two minutes.
The last bit took less than a minute.
The 2 inch thick branches took about 8 or 10 chops and less than 20 seconds to cut.
Here's a 4 - 5 inch seasoned Poplar. Less than two minutes.
On the smaller 2 inch branches of the Poplar one swing would go 3/4 of the way through.
And the 1 to 1 1/2 inch branches could easily be taken in one swing.
I did a lot of chopping of very dry, hard wood on today's hike. Towards the end of the day I visited a campsite I stayed at last summer
and took a rest and examined the edge of the Mistress. There was almost no perceptible loss in sharpness. It was still hair popping sharp. No edge rolling or denting. Nothing. Freakin' amazing

The only noticeable damage came from when I didn't expect the blade to lop off a branch in one swing and dinged a rock, not tremendously hard but still with a good deal of force. The ding in the blade is just barely visible to the naked eye and is only really noticeable by running a fingernail along the edge. Pretty amazing.
Simon you really did an awesome job on this blade, thanks :thumbup:
All the knives that went on today's hike.
