Just finished this a few days ago, the flask is made from vegtanned leather, and it's soaked in beeswax to waterproof and stiffen it. The stopper is a piece of cedar attached to an old wine cork. The strap is 7 strand black paracord, braided together to match the style of the celtic knot. You can see a complete writeup of how I made it, here.
Hi, I'm Stephen Stumbo, I'm 18 yrs old, and a self taught knifesmith/blacksmith. All through my childhood I've had affinity for blades, probably starting with my first pocket knife. At 12 I tried to grind a knife out of a sawzall blade, and was so proud of how it turned out. At 14 I convinced my dad to help me make a forge so I could try blacksmithing. After building the forge I had a rough time getting started, but after meeting a local blacksmith and getting some tips, I went at it. About a year into blacksmithing (2009) I decided to try my hand at making knives. I started out terribly, but I've slowly been progressing to where you see now. Take a look around, and let me know what you think, you can also find me on facebook to keep up with the goings on around the ole smithy.
