Lay the spear on top of the straight edges at 90 degrees to the surfaces with as much of the spear point end protruding over the one edge. Now roll the spear by using only a finger, putting as little downward pressure as possible, preferably over the straight edge furthest from the spear point.

While rolling, watch the spear point. It should have as little wobble as possible. The more it wobbles the more it is bent. If the spear has difficulty in rolling then it could be very bent. This bend can be caused by a previous fish or, a gun that was mishandled, stood on, poorly transported etc. It is also possible that it could also have been bent from new. It is also possible the original manufacturer was not vigilant enough when straightening the steel or was not aware the supplier had supplied steel that was not top quality.
