Sharpening Tip:
I use a cheap 1x30" Harbor Freight belt sander, starting medium and working down to strop like most everyone else...
The difference.. is a neat trick to thin the edge, at just the place it needs to be... on a fat blade, the belts will often leave too obtuse of an edge for my tastes and to thin it out, this method works wonderfully.
I wear a thick/heavy leather glove, and apply pressure to the backing of the belt. That is it. Sometimes using the seams of the glove, sometimes using the smother rounds over the fingers.. etc. You can play with where to pressure and how, and have various edge results.
A series of colds had me floored and in lock down for a month, and I have been playing with various techniques with my spurts of wellness.. and am amazed how hair splitting sharp I got my AK with this method.
play at your own peril.
