Today i did a little hiking in the woods near my house, so i could play with my GSO 4.1 some more.
On the trails there is always some clearing to do, and this time i got to baton 4 narrow spruce trees (diameter 4 to 6 inches) that had been blown over the footpath with the use of my recoilless hammer i took with me for the occasion (didn't want to find a suitable branch first and the hammer strikes more precise)
Due to the nylon heads there is no chance of damaging the back of the knife, and thanks to the lead shot filling it still has quite a lot of impact.
At home i took a quick pic and then cleaned the knife from resin etc.
On inspection by daylight there was absolutely no damage visible to the edge with the naked eye: no chipping & no flattening.
Doing the same with the magnifying glass in my SwissChamp and with the same lighting conditions i could spot some extremely minimal edge damage: one spot where (judging by the scratches in the bevels) the edge was probably hit by a tiny grain of sand and some very very small spots which reflected a bit of light.
Thus ends my nitpicking.
The sharpness of the edge had decreased from treetopping/hairwhittling to an easily shaving sharpness: the edge still shaves the hair on the back of my hand and my calf with the greatest of ease, both with the growth as against it.
NB: this was done with the edge reprofiled by me to an ever so slightly convex 30 degrees inclusive angle, which also is a bit finer in edge finish than straight from Survive! Knives.
Good stuff this M390 steel,
