The Di Acro shear is the best built shear.
It is so heavy duty that if packed correctly,
there should be no damage.
I have had a used Durston rolling mill,
Di Acro shear, heavy magnetic pin polisher,
and an antique wire draw bench shipped
with only one piece suffering minor damage.
Usually the company selling a shear is
familiar with proper packing for shipping.
The main issue would be condition of
the blade, worst case scenario, it would
need to be resharpened.
I have had my shear 15 years, never
had to sharpen the blade, cuts like butter up to
18 gauge, 16 requires a bit of strength,
and starting two inches from the left
( use a steel block against the guide) makes
the handle easier to pull down.
