I tried to cut a square hole with a jigsaw. I flat out failed as the
cut had a wavy appearance. I am using nice Bosch jigsaw.
What I did was to drill a hole and then approach the line. I had a
aluminum straight edge. I found that the angle I cut had caused the
blade to bend.
I have a new piece of stock and I am going to try again. I did
decide to ensure the blade will not bend yet I keep thinking I will
have the same issues. I searched the groups but did not an exact
answer. Just looking for some guidance.

How thick is the material?
Be patient, it is slow work.
Drill your starter hole and proceed as before but STAY ABOUT 1/16TH AWAY
FROM THE LINE. Clean out the scrap with a mallet and sharp chisel. If you
have one, use a corner chisel to get nice square corners.
Your technique needs improvement. The answer is simple.
If you put sideways pressure on a jigsaw the blade will bend and
the cut will not be vertical. You should be applying only downward
and forward pressure to the saw. Try sawing on a scrap, both with
and without sideways pressure, and you'll see what I'm talking about.
Also. Don't use a fence or guide on a jigsaw as blade can have a
drift and not cut parallel to the edge of the sole plate. This will cause
sideways forces as you cut. I have found free hand is my best bet.

Us poor folk, if we don't know how to do something, we practice on
scrap. I'm still trying to figure out how you bent the blade.
Custom philosophizing done. No job too small; must be indoor work, with
no heavy lifting.
Let the saw do the work, ease it forward. No side to side motion. Use
plenty of lighting to watch the guidelines. Drill a hole in each
corner so you can turn the saw. Finer teeth on the blade may help.
