Ah, good point
.
I personally think that the whole "magic" was probably some mechanism that was beyond the understanding of Hobbits or Men.
Say...something like the toy cars with a spring insde that once pulled back go forward with quite some speed.
A Hobbit would probably think it's magical that once you pull the car it then moves forward by itself.
I know that we already have many examples of great smiths, just wanted to add two other important ones - Celebrimbor and the legendary Enerdhil of Gondolin.
