I think that the term "laser sharp" or "laser sharpened" has the same meaning
when applied to knives that it does to fishing hooks -- except that hooks have
very sharp points whereas knives have very sharp edges. In the case of "laser
sharpened" fishing hooks, the points are ground to a very sharp state using
conventional grinding processes -- I think that they use a carborundum abrasive
held into wheels or cups by an epoxy binder, much like the grinding wheels used
in machine shops to sharpen tools used in standard machining or like the
carborundum "stones" used to hone knife blades. "Laser sharp" fish hooks are
then processed using a chemical etching process -- proprietary to each
individual manufacturer, but almost certainly using a mixture of acids -- to
remove irregularities or burrs in the surfaces and so make the edge more
perfect... sharper.

The reference to being "laser sharpened" is, I believe, a marketing or selling
term which alludes to the blades being very accurate and precise -- like a
laser beam used to point precisely and very accurately. I believe that the
alloys used to make such knives are pretty much the same as those used to make
other knives, and that laser heat treating is not used to make the metal
harder... As far as I know, the sharpening process should not make the blades
stay sharper any longer than any other knife blades of the same general design.

Єдина відмінність - там не згадують про якісь вимірювання за допомогою лазерів, лише порівняння з гостротою лазера, і я думаю, що це навіть ближче до істини! =)
