See, this is exactly why Smithing is a wonderful concept. Making your own weapon makes it that much more personal, if done properly. But for me, making a daedric sword was pretty much, "Go to the general store, buy a daedra heart, go to the smith, buy 3 ebony ingots, make sword, woooo." The potential personality of it doesn't seem to be there, somehow.
The personality of it isn't there because all you did was make a stock-quality sword with materials that have become common. The true personality comes out when you create something that no one else can touch by creating and tempering gear that's made of materials the world is only just starting to find, enchanting it, and naming it if that's what you feel like doing.
Different games will be different experiences. In my experience, I went around the world mining everything in sight from level 1 on, to the point where I could power level my smithing off of just the materials I had found. I had become such a high leveled blacksmith in relation to my other skills that the materials I would need to create my masterpieces were not yet available in any shop, and if they were, they were
eventually sold
maybe one ore at a time, which is not even enough for even a weapon. It'd take days of searching far and wide for those materials before I could create a set of armor with what I had, then top it all off with a weapon.
In my case, though, I also became a rather good Alchemist and Enchanter, and I found the Smithing enchant early on, so when it comes time for me to smith me some new equipment, it becomes a journey of hunting for Grand Soul gems to enchant my Blacksmithing gear, complete with a Blacksmith's Apron that I found in a Bandit's cave, reagents for a potion that would fortify smithing, and culminate in my gathering of the materials I would need to complete a full set of armor complete with weapon. When the time comes to finally down my potion, sharpen my sword, and temper my armor to perfection, it is the end result of a grand adventure that took many playthroughs, and you can bet your left nut that I will don my Legendary weapons and armor with pride for weeks to come.
When I find extra high-level loot, I don't see it as a new tool in my arsenal, I see it as something I can sell at a high price, since my custom-tailored equipment is far superior. I'm not yet to Ebony smithing - I'm level 26 and have 76 Smithing - but I'm within arm's reach, but I just found my first Ebony Greatsword in a loot chest. I don't use it yet because it's a dull, useless thing that's completely inferior to my Legendary, 81-damage, Grand Soul Fire-enchanted Elven Greatsword, but once I get good enough to improve it, it will be my greatest work yet.
