To All: Often times we have the need to create small but accurate shapes in metal or wood. {{SNIP}} Collect all of the blades in a shallow pan and cover them with an eighth of an inch of motor oil. *Now set the oil on fire. *Allow the fire to burn out. *It's going to be smokey as hell so you want to do this outside of your shop. *When the fire goes out, tip the blades out of the shallow pan onto a piece of iron and allow them to cool. Once the blades have cooled you may continue with your sharpening. They should take a razor edge. *If they crack, you've either left them in the bomb too long or you've cooled them too fast. *The tempering (ie, burning-off) should not effect the cracking one way or another. Robert, You are simply amazing. *Your directions fit right there with what all my father attempted to teach so many years ago. *(The forge is long gone). But the tempering process . . . is there a method less smoky and noxious? For the faint of heart who live in an area where the neighbors are less tolerant of *flames and smoke? Thanks Flash (Yeah, my neighbors only put up with *a certain amount of disturbance, and the Mayor is not exactly a personal friend) Quench in used cooking oil, smokes but less fire, and anneal in a toaster oven to around 460F. http://www.caribooblades.com/makingahook.html Karl |

A constant problem with the Internet is that it is impossible to sort the wheat from the chaff. Almost everyone has an opinion they are eager to share but much of the time that information is flawed; often not even tested by the person offering it up; something have only HEARD about and which may be repeated incorrectly. Go look at the site Karl mentions. This fellow knows his onions. -R.S.Hoover |

Your online hints and such have gone into a folder marked "good stuff-how to's" and I back it up, so I don't lose it in a crash. You have made me think of many new possibilities. Shoot, I'm even sharing things (like the carbon blade thread) with co-workers that is currently making knives with his ag students. He is using old circular saw blades for the stock. -- Jim in NC |
