ParaMilitary in the garden

[BBQ BOY]

One thing I learned today is dirt dulls the living day lights out of a sharp knife.

i've learned that a time ago also, first time shaving sharp went out for some garden work and it didn't cut a piece of paper

[Seanski]

oh yeah I took a byrd raven outside once to till some soil and the edge became
duller that the edge of a spoon. You've more guts than I do taking a Para out
though.

One thing I learned today is dirt dulls the living day lights out of a sharp knife.

In high school, I read a short story (possibly a Steinbeck) about a boy who kept his dead father's (I think) knife sharp by stabbing it into the dirt. I don't remember too much else about it, but that part always stuck with me because it seemed like such a strange idea, and I wondered if there could somehow be some truth in it.

i'm curious, can someone explain why dirt dulls the blade?

[nomotiv4all]

It's easy enough to Google it, but dirt contains abrasives that dulls chain saw chains, knives, pruning saws etc etc. imho it seems shaving sharp knives might dull rather quickly on account of the extremely thin cutting edge even if it is a very hard metal.

Dirt contain hard particles such as silica (glass), aluminum oxide (sharpmaker rods) among others, so essentially you are dragging the edge across sandpaper.

magic?

The culprit is quartz in the dirt, that will dull a blade fast...
