The bottom mount, drag, chape, or whatever. Wow. The site that shows this has been disabled. OK. to start, you need to make a steel form. The drag is a two piece item. I use 3/8" hot rolled steel, but 1/4" will do. You shape the bar steel to the exact profile size of the leather sheath bottom/point area, making it a few inches longer than you want. That gives some extra for you to hold in a vise if needed. You then round of the sharp edges, making them pretty rounded, but leaving a flat in the middle all the way around. Make these edges as true to each other side to side in roundness as you can, and roll the point area over also, making sure it doesn't make a knife edge. No need to polish, but don't leave them ragged. From the sheet metal you chose to use, mark the leather sheath profile on it. Then add about a 1/4" to this marking, and cut two of these out. Cut them longer than wanted so you can trim them back if wanted. One will be one side, the other, the other side. Put it all in the vise. Use a block of smooth wood on the side of the piece that will be visible when finished, the form is resting against the other vise jaw with that extra 1/4" equally all the way around it, and a little more than one half of the metal tip showing above being clear to hammer on. These halves have to be kept centered on the form with the vise tightened well down. Now, you need a piece/block of hard wood like maple. You do not hammer the metal directly, but hammer the hardwood to shape the metal to the steel form. A hammer the hammer operation. The wood will not mar and mess up the surface of the piece as a iron hammer would do. Start the shaping at the point. If possible both point sides at the same operation, then turn it all over and work the other edge. Go back and forth until the piece is fitted well to the form. You may need to anneal the metal a few times as you go along. Once shaped, lay the sheath in it and see how well it fits. OK these two halves are way over sized, so I choose the back half and start trimming on my belt grinder and table deck sander until the piece fits half way up the sheath side. The sheaths will have a taper in thickness according to the blades distal taper so the metal halves taper in thickness just as the blade does. With the back side fitted halfway up the seams, the front side is done the same. Down nearing the point, it is well to fit the halves without crowding the sheath in that zone. As long as a taper is evident, it is enough and allows room for adjusting if needed. To be continued.
