After doing a chop-off with the KZ and it's immediate "knife" competition which it was pretty emphatically the winner ... I decided to see how the KZ compared to the GFB SFA ....
Here are the two ....
I decided to take down the trunk of a tree which had been snapped by high winds as the liklihood of it growing again in the shade of nearby trees was remote and it would come in handy for firewood ... here is a pic of the trunk and I needed to drop it in the same direction I took the photo where there was a bit of a clearing ....
I started on the trunk using the GFB SFA to open out the main under cut where I wanted to drop the tree ....the Axe easily sorted this .....
On the other side I started the upper cut with the KZ .... and this was able to "bite" as deep as the Axe ....
The best photo I have to compare the two is this one ....
On the right you can see beneath the main area of cuts the last strike I did with the KZ ... the depth of the cut is very impressive and it only took a few more strikes to bring the wood removed on the upper cut down to this point ... the extra blade area of the KZ would remove more wood with each cut across the trunk than the Axe .....
The Axe however was a lot easier to use .... you needed more swings to enable the Axe head to cover the diameter of the tree ... but it was less tiring and over the same period of time they were both about equal in depth achieved... the Axe though needed to be brought down at a steeper angle to cut as deep and removed as a result a lot more wood ....the KZ could bite very deep in a lot smaller cutting area ... wasting less wood as "wood chips" and this can be seen from the following pic ....
Looking from above you can see that each had more or less gone halfway into the tree trunk ...the Axe being the lower area and the KZ the upper ... but look at the final cut on the upper section that the KZ did to cleave through the trunk of the tree to fell it .... in the hard wood section of the tree the KZ has cut as deep as the blade section of the knife and at a fairly flat angle ....which felled and dropped the tree by basically cutting it clean through .... I did I admit put a bit more effort into that one cut than the others just to see if it could do it ....and I was quite suprised with the way it managed it .... I tell you ...there is a LOT of power you can put into this blade
:thumbup:
You can see the flat top cut and more angular under cut in this pic together with the trunk where it fell ...
It is not a clear pic because by this stage my hands were shaky from chopping and round the back of the trunk is the KZ embedded in and just sticking out on the left hand side ... but it gives you an idea of the two cuts and where the trunk dropped.
