what's it called

Gentlemen

I have a tanto that has what looks like added metal in what I think were openings in the blade steel.

The repairs are very small, and I would think it very difficult to do with the precision I see here.

 

Unfortunately, very hard to photograph,  The repair is 1 -32nd by 8 -32nds of an inch
