Ain't nothing like good ol'American kno'how.
Looks good enough to use. But that's a lot of work.
Maybe it will warp again when it thaws?

Ok weather thawed this afternoon. The bend shown in second photo above is about the extent of the original warp, on the opposite side of handle. Here you can see results more clearly. Pick is resting on its handle head, so it should be perpindicular to floor instead of this tilt. However most of the warp is at the head end, so straightness from below the pick head to end of handle isn't too bad. The chalk line reflects both the remaining warp and how the handle end twists a bit counter clockwise.

So the proof will come with the using. I have some overgrown mine dumps in mind for its first outing.

Think I should sharpen the tips?  Sinks into rocky soil just fine as is.

I am hoping it proves more durable than the big box stores offerings.  I've bent Lowes picks if used for anything tougher than dirt/clay.
