TheoRockNazz Posted August 19, 2012 Share Posted August 19, 2012 Howdy guys, Today I have two new blades for your consideration. First is a file given to me by Owen Bush when my class with him ended, reforged into a fighter similar to his own seax style with a twist. Blade was normalized, forged, annealed & drilled, normalized, differentially hardened, then double tempered to a delicious gold color at 395F/202C. The fittings are low layer damascus that's been etched then lightly repolished so only the topography shows, with steel pins, brass spacers, ebony and mosaic pin. I live in NYC, so when the blade was finished I just ran it over to Bill at MastersmithS, where it was added to his collection and soon to be on his website - only my second accepted knife! Here's Bill with it: The second is a damascus utility knife of old jackhammer bit steel (S-5?) and mild steel that I had forged a while ago in London (at Shelley Thomas' forge), but never handled until back in the States; handle is bamboo with mosaic and brass pins. The blade is differentially hardened tempered the same as the first; but has a small cold shut that I am not thrilled with, yet doesn't effect its cutting ability. I'd love to hear what you guys think, Theo Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted August 19, 2012 Share Posted August 19, 2012 Machinery's handbook says that the S series would make good jackhammer bits and that morphed into many junkyard steel lists stating that jackhammer bits were made from S series steel. However as has been posted here before: From Grant: JACKHAMMER bits have a hole down the center and go in a percussion drill (jackhammer). Paving breaker bits are solid and go in a paving breaker. Yeah, I know, most people call 'em jackhammers. Having owned a company for 18 years that produced millions of them probably makes me a little pickier than most. For me, if a customer ordered a 1" x 18" jackhammer bit, I had better send the right thing. As an aside to this, I've had just about every bit made spectrographed and never found one made from a tool steel. The largest manufacturer (Brunner & Lay) uses a modified 1045 for all their bits. Vulcan used to use 1078 (a high silicone 1080) but have changed to a boron steel in the last few years. Most others (Delsteel, Pioneer, Ajax, Tamco) use either 1078 or 9260. I Had good success using 8640. You only have to remember that B&ampL is water quench and the others are oil when you use them to make other tools.

TheoRockNazz Posted August 19, 2012 Author Share Posted August 19, 2012 Cool, thanks! If it was something more exotic that might explain the cold shut... though damascus is new to me and I need more practice as well. I had patternwelded a bundle of billots of the same mix before leaving the UK, which I'm now using entirely for fittings because it uses mild steel.

TheoRockNazz Posted August 21, 2012 Author Share Posted August 21, 2012 My work is now featured in the MastersmithS collection (aka NYC's local weapon shoppe)! I am honored.http://www.beautifulblades.com/products/show/1470# Quote Link to comment Share on other sites More sharing options...
