Notes
Material is currently 316 stainless, I would like to change it to A2 tool steel. Cost analysis needed. Advantages are heat treatability, better all-around knife steel. Disadvantage is additional cost, need for hear treatment. Need to talk to marketing. Current process is to machine this part. Look at making by other methods.
Note: Current models may not reflect the scalloped blade design. Need to change models to reflect this. Marketing wants the stepped blade.
