Line 5:
Once forged into the rough blade shape it was cooled and annealed to make it soft enough to work and then the [[Tools/largelinisher|large linisher]] was used with a zirconia belt to form the blade into the final shape of a rondel dagger, which has an unusually thick and heavy blade that tapers along it's entire length. Hand filing was used to shape the transition between the blade and the tang so it would sit snugly into a handle.
[[File:handgripdetail.jpg|400px|Detail of the handgrip]]With the blade shape finished attention turned to the handle which is made up of identical pommel and guard sections and a hand-grip. The hand-grip was made from some (probably) teak that was around the lab which was [[Tools/pillardrill|drilled out]] with a 5mm bore all the way through then mounted up on the [[Tools/woodlathe|wood lathe]]. The grip was turned down with finger grooves spaced to my hand, then sanded with increasingly fine emery paper until it was completely smooth, it was parted off and then treated with 8 coats of danish oil, sanding between each coat to give a smooth but still gripy surface.
As the original, being an archaeological find, was a little short on detail I decided to improvise a bit on the guard an pommel piece and take inspiration from other daggers from the same period to fill in detail where the original was lacking. These 2 sections were made from a sandwich of the same teak(probably) used for the hand-grip in between 2 sections of octagonal stainless steel with 8 rivets holding each sandwich together. Stainless steel obviously wouldn't have been available to the original makers but given that these sections are in contact with the hand when held, and I don't have servants to polish them every time someone touches them, stainless seemed a sensible choice!
