I did not like this design from the get go, but I did it, the frame and scales are of steel of the same kind, he is going to fully engrave the scales and then blue them, it will have a nickel sheath that will be engraved, you needed to be able to take it all apart to blue it, this is the only way I could think of to do it and get it back together after engraving and bluing and try and keep the weight down, not crazy about things that come apart, used four line up pins so it will go back and fit seems to be working at this time.I am going to make a plate to screw the scales to that will go in the engravers vice so as not to distort the scales, am hoping it all works, this thing has taken a lot of time, hope it dose not go to pot.
