Restoration knife with Lines on blade 

I restored a rusty knife, look at these lines on the blade, the blade is interesting. I do not know the method of making this design on the knife. But in any case, I'm glad that such an unusual blade was under this rust. I bought it for the price of two loaves of bread, very cheap, along with another chisel tool, a hammer, 6 blades without handles, the two knives were completely intact, I will fix these things, and I will make a video about this like, and click on notifications, thanks for stopping by write something in the comments, thank you
