don't think knife.. or axe edge.
a straightrazor with a hollow grind would indeed stick... but we use different edge grinds ( angles) to provide a different type of cutting
surface.
you can take a 1/2 inch thick khukuri with a shaving sharp convex grind, and chop a tree as thick as your thigh in half without sticking.
my 1/4 inch thick WSK will shave your face, and chop a fence post into kindling.
No sticking.
You're probably right then. My only experience with blades getting stuck is from sawing down trees. What seems to be happening is that when enough
of the tree has been sawn through, the weight of the trunk bears down on the sawblade, and eventually makes it stick.
Do axes ever get stuck in trees? Is the problem that they are simply not sharp enough? Or is it maybe the degree of force, or lack of same, which
allows the material to bear down and cause the blade to seize?
axes do stick for a number of reasons.
Mainly the combination of sharpness and grind dynamics.
New axes usually don't stick.. however when they dull, and are sharpened improperly, the edge becomes thinner, and flatter rather than convex.
with a very wide blade, flate ,sharp grind, the blade of the axe cuts depper and becomes wedged in th soft wood as it expands against the axhed's
sides.
here's a good site that explains the basics of blade grind dynamics.
