Offset Spatula HT Questions?

Good Morning All!

I've been tasked with a spatula set from a Chef customer that I have made knives for in the past. He specifically wants an offset pastry spatula set. My question relies with the HT of the spatula in order to perform as intended. They have to be thin and somewhat flexible. I have some .050" 1075 stock that I plan to work with. I believe I will have to surface grind the stock thinner in order to get some flexibility which is no problem, but I don't have much experience with super thin material. I will also need to brake/bend the spatulas twice in order to get the offset. Again, I'm not to concerned with actually bending the material.

The concern is the bends coming out or changing after heat treating the spatula. How can I keep the bends consistent during the heat treat process? Normalization? Jigs to hold the form? Thoughts?

Similarly, what would you temper 1075 to in order to maintain the best flexibility? Since these do not need to be cutting tools, can I temper to a relatively soft to achieve this?

Thanks!
 
If I was making an offset spatula, I'd make it out of AEB-L, then temper it to a spring temper. If I was trying to keep it from bending, I'd make a plate out of angle iron or something similar and clamp the spatula down to it, through the tempering process.
 
I agree. Normally I’d choose a stainless like AEB-L, however my customer requested carbon with a etch/stonewash.

He has an in depth process but maybe you can get some ideas from him
