"jump", verb, in iron-working

[George Thompson]

>From an advertisement by a blacksmith, in Delhi, N. Y. (near Oneonta):

            A supply of new axes will be constantly kept  on hand, and old
ones jumped at the shortest notice.

            Delaware Gazette (Delhi, N. Y), December 7, 1825, p. 3, col. 2


I have no idea what this guy is offering to do.  But it doesn't seem to be
covered by the OED, whatever it is.

 *13.* *a.* *Iron-forging*. To flatten, ‘upset’, or shorten and thicken the
end of a rail or bar by endwise blows. Also *transf.*
