The next one is a very interesting style of historical knife. I found a historical piece of crucible steel in the woods that once seemed to have been a cold chisel, and it has a carbon content of about 0,7-1,00%, too, when compared to file steel and spring steel. I have always called this blade shape a "Kopis", but morphologically it is more correct to call it a Sica, a knife made famous by Dacian people in the iron age. There is a whole world of variations, the one thing in common is that they offer one sickle-like edge (the word "sickle" derives from Roman "sicula"-tiny sica). The earliest examples from the Hallstatt period (from 890BC) are often strongly curved with little or no straight tip section. Later on the tip section was becoming more pronounced for some examples resulting in a shape more like the blade I forged. The integral bolster is not authentic, at least I do not know any examples of this, and this would be logical if you keep in mind how precious iron, and more so, high-carbon iron of good quality had been at the time.
Look at these excellent articles (in Romanian language):
It is a most fascinating type of knife and I plan to do more of that stuff... watch this place!
