dps9999 Posted June 8, 2016 Share Posted June 8, 2016 hey guys so today i was working on a blade and these weird circle like things show up on the blade....at first i thought it was a finger print or ya know how while grinding you dip the blade in water to cool and the water dries and leaves a spot that is exactly what this looks like but this wont wipe off or even grind off! i started to notice it about 220 grit and 400 and 600 (thats where i stoped for the day since i was getting fustrated) but these marks are still there in the exact same place (so i know its the same mark not a series of them) i have NEVER seen something like this and its not to distinct like i said looks like a fingerprint and you gota catch it at the right angle ...does any one have any idea...the only thing i can think of is some kinda defect in the steel or maybe i did something in the heat treat?? i am clueless on this one Quote Link to comment Share on other sites More sharing options...

Nobody Special Posted June 9, 2016 Share Posted June 9, 2016 Possibly a decarburization zone, or accidentally created a hamon like effect from having the tongs on the blade and not hardening properly at that spot? Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted June 9, 2016 Share Posted June 9, 2016 could be faery rings where are the pics? Quote Link to comment Share on other sites More sharing options...
Nobody Special Posted June 10, 2016 Share Posted June 10, 2016 Nah, fairy rings are made of mushrooms, and besides fairies avoid cold iron like the plague. Usually more of a problem with aluminum or at cosplay events. Quote Link to comment Share on other sites More sharing options...

dps9999 Posted June 10, 2016 Author Share Posted June 10, 2016 hey guys sorry about the pics....my camera is in my sisters car and she hasnt been here ill try and get something up as soon as i can.....its not from tongs i HTed it in a even heat oven and used long pliers to grab th back edge of the handle dip it in the oil and as soon as it gets in the oil i put a hook through a hole in the tang...i did keep grinding this since its suposed to be polished and it did seem to go away a little the higher up in grits i went its still there but like a holagram you can only see it in the right light Quote Link to comment Share on other sites More sharing options...
Crazy Ivan Posted June 10, 2016 Share Posted June 10, 2016 Did you mix oils possibly? Different viscosity in the oils leading to random differential hardening of the blade comes to mind. Never seen or heard of this, but it sounds possible. if it looks like a hamon, that's what I would theorize. Quote Link to comment Share on other sites More sharing options...
dps9999 Posted June 11, 2016 Author Share Posted June 11, 2016 no mix oil is parks 50....i am going to try to get a pic up later when i get the camera back Quote Link to comment Share on other sites More sharing options...
