It's a great knife steel. my EDC boker stockman has C75 carbon blades in it. Which pretty much a Euro 1075. take to critical, then quench in a proper quench oil. A temper at 400ºF for 2x2 hours will produce a very nice blade

I have had a bunch water jet cut. Can be pricey for the first due to setup costs. To be worthwhile I only waterjet complex shapes that require alot of grinding, simple shapes I can cut on my bandsaw.

thanks how do you heat treat the 1075

I waterjet 3/16" 1075 for throwers. Most waterjets cut holes slower than the profile (in inches per minute), so if your design has tons of holes (in the handle tang, for example), it will be a pretty expensive cut.

I heat-treat in a little propane forge, quench in parks 50 oil, and temper in a toaster oven with PID control.

thanks how do you heat treat the 1075

The Heat Treater's Guide says the following for 1078 (the closest listing to what you have):

Hardening. Heat to 1500 degrees F. ...Oil quench sections under 1/4" thick.

Tempering. As-quenched hardness approximately 65 Rc.

They just show a graph for hardness after tempering. 300 degrees will give you about 62 Rc, 400 about 59 Rc, and 450 about 57 Rc.
