They don't need to be as beefy as an HI Khukri because the are not designed to do the task of your average Khuk. As far as the magic stone. I am a geologist by trade and from what i understand is they use granite pulverized which contains mostly calcium, sodium and potassium feldspar and quartz all of which is harder than steel and also softer minerals such as biotite, muscovite, and other softer minerals. HE he. I do know my mineralogy but what i don't know is how they process these compounds with minimal tools and how they apply them to to their trade (magic powder cement). That is their magic and my natural curiosity is killin me! I would literally give up my day job to spend time with these craftsmen to learn and propagate their knowledge. This art needs to be carried well beyond our generation. I havent forged a knife yet but I have made a few knives from blanks and modified pieces of steel from all kinds of sawblades, and whatever I can get my hands on. I do plan on a forge but Im still washing dishes outside, have no plumbing, bathtub etc. so gotta finish my house first. I do have internet tho...Ha imagine that! As far as anvil you can sometimes pick up pieces of railroad track on secondary market for about 40 clams a foot. They make great anvils. If your serious about that let me know and i will get you something! I too overworked my first Chitlangi and rolled the edge really bad in two places but was my ignorant mistake. Thought i was gonna puke... it made me sick to my stomach. I unrolled it on an anvil like you speak of by using a chunk of copper to tap and unroll it back into place without chipping it. Been fine ever since! I still love my Chitlangi. Im jealous of your new 21" btw.
