Story telling, Creative, mythical description for selling a product

Looking for a very creative description for selling a Hand Forged Railroad Spike Knife, i have attached a picture of the knife. To Get a better picture of what i am looking for, Picture something set place in the time of the show "the whitcher" Your about to go out on a great adventure when you come across a demi god that is a blacksmith, his powers are forged into the steel that he makes his knifes with. Creating a knife that will forever grant you the mana and strength to carry you anywhere you go. The knife is used for skinning, and just a general purpose knife, Similar to like a "pocket knife" I am looking for something very creative and mythical, something that is almost like a Viking talking about the knife and the blacksmith that created the knife. Something that really makes the blacksmith sound like a ancient mythical demi god who is handsome, strong and a family man with powers. also would like it to reflect the strength of the knife due to it being made by this mythical blacksmith. This doesn't need to be a long description, just needs to be quick and creative and i am looking to have this completed today i know this sounds silly but its who we are. :-) Thanks!
