I have had a series of playtimes with this knife/saw and here follows my personal appraisal and opinion.
First impressions;-
Rambos EDC
When I first looked at it,I thought it was dog ugly.This is still an opinion I uphold.It looks too military for my personal taste.It also has plastic handles.Its a high tech, high performance plastic called zytel,but in plain English its still plastic.It was also big enough for shrek to use and made my hand look small.
The knife blade is a bizare shape following the contours of the finger grooves in the handle so as to fit flush when it is rotated to become a saw. It also has a gut hook which is not needed unless you are slaughtering lots of animals which also contributes to make it an even uglier shaped blade.
The knife is however surprisingly light in weight at only 6oz.
It was mostly sharp as I recieved it and was hair popping after a couple of strops.
I tested the saw end first and the action of the revolver was smooth and the lock positive when I swivelled the blade to the saw end. The saw worked well on branches upto about 2" (50mm) and I sawed through a variety of timber including Cypress,hazel,birch and hawthorn as well as a couple of well seasoned apple branches about 3" thick.Which proved a bit tougher and caused me to sweat.
The saw was flawless in performance although the shortish blade meant some effort was required.I also used the saw to make the cuts for a large figure 4 trap mechanism.It was clean cutting and accurate to use. I rated it quite highly and would be happy to use it to make a leaf shelter or cut poles for a camp.
The next stage of testing was the sharp end which is 6" long and sharp.I found the guthook was good for opening hay and straw bales but the cutting edge would also do that.As the blade was long by my standards i decided to cut down a few square metres of nettles as you do when making cordage or thatching a shelter.It was great at this.Little weight meant that the Knife needed swinging and the edge stayed sharp and cut through with little effort.The knife is flat ground with a secondary bevel.it sliced and diced in the kitchen pretty well and was good on feather sticks and sharpening sticks.
Carving a spoon,as Marts attempted was as task too far for me as I tried to choke up on the blade and in order to get control of the tip of the knife I had my entire hand on the blade.Sharp and dodgy!
The concept of this tool is superb and works faultlessly but I would want to see a 4" plain drop or spearpoint blade on it.
If it were mine I would convex the blade profile.I would also change the plastic handles, which make a good tool look cheap.
I would be happy to be lost in the woods with just this tool as it does function very well despite its military background and poor aestetics.
