I think this is a great item to help skill-up your blacksmithing if you are a Barbarian.
If you loot a fine steel weapon, you can put it in a forge with a water flask and it becomes one or more small bricks of high quality ore.
So, all you really buy are water flasks for 1 silver each and the needle and thimble molds for 2 gold each.
The sewing kits sell to vendors for 9 gold, so you can even make small profit while skilling up.
