[Marvel] how were wolverine's claws tempered? Or sharpened?

So,  we know the adamantium was in liquid form when it was grafted to wolverine's skeleton.  But in order for any metal to be durable- hard enough to hold an edge,  flexible enough not to be brittle,  etc.  So my question is,  how did the weapon x program accomplish this after they injected the liquid metal? 

Secondly,  how did they shape and sharpen the blades?  And how does logan hone the blades?

They accomplished it by pouring into a mold that was around wolverine. The process binded it to his bones, but the claws were bound to bone-claws at the base but also molded to be that shape, which is a good balance of practicality and actually fitting in his hand/wrist.

It doesn't need sharpening. True adamantium is indestructible. It's not a regular metal in Marvel. It is actually impossible to destroy or deform it (outside very powerful magic) once the liquid has set. The molds for the claws were shaped to make a very sharp edge, and so the claws will forever be that sharp.
