Default 1095 steel help

Looking to make a bent spring clip out of 1095 spring steel 3/4" wide x 2" long by .022" thick. I need to make a 25 degree bend 1" up the length and I am looking for advice on how to form this. I can get hardened and tempered 1095 from McMaster but not sure if it is able to be bent? Any help would be appreciated.

FYI for anyone interested. I was able to form the clip mentioned above using a 1/4" bend radius. At first I tried hot working it, but no matter what I did it kept annealing the metal. I experimented a little more and found at a 1/4" bend radius I could bend the piece to 90 degrees. Anything less then 1/4" and it would snap almost instantly.

ulyscol - Here is how to do it - from an old timer.
Cut your steel to size, round off all edges with emery - important!
Make your bend or form.
Now hang your piece from a wire - a paper clip will do - and use a propane torch to heat to a cherry red. Quench in oil.
On the same wire- over a soft flame, with the oil still on it - hold it into the flame untill the oil burns - than quench. Repeat this for five , six or seven times. Heat -quench and you will come up with a perfect spring. Nice and shiny black. Test it and you will be surprized as to how good it is..If it comes out to soft - you heated it to much. A little practice makes perfect.
In the old world this is called tempering.
