Knife Making
I thought knife making would be an interesting metalworking topic. I mean
we got tools, quality metalworking, steels, heat treating, forging, and on and on. So if I get my shop building and have more convenient access to my equipment, I'd like to make some quality knives. For one, I want a blade of D2 because I hear it's almost stainless but holds an edge real well. So if I could come up with a nice folding knife locking mechanism I could design in CAD and machine with the CNC, I could use that design to make an assortment of blade styles and handle styles. One thing I noticed about knife making is that you can get a lot of money tied up in equipment, and I always like the idea of getting more equipment but not spending lots of dollars. I thought I could make a knife makers grinder by using tubing in the Reese hitch size ranges, maybe using polyurethane wheels ground true for contact wheels. The heat treating furnaces are quite high too. Maybe get some kiln firebrick and heat elements, fabricate a frame to hold the bricks, and use an industrial ramping temperature controller with a solid sate relay for temperature control. Then I can set it to soak, ramp to temperature, hold, then switch to tempering temperature. Also it seems one of the controllers would be great at annealing, heat, soak, let it cool at specified rate at the critical temperatures. Anyone here do any knife making? RogerN |

It's learning how to treat the various areas of the blade to keep the finished blade from becoming a mess that's the hard part. -- Steve W. |

Anyone here do any knife making? RogerN There's a book out by an editor of Blade magazine called "The $50 Knife Shop" or some such. Probably would be $100 now. Guy has some funny ideas about metallurgy and what goes on with hardening and tempering, but his shop ideas are sound. Has things like how to set up a smithing outfit, makeshift hardening setups, not so makeshift furnaces, build belt grinders( worth the price right there) from skate wheels or shopping cart casters, anvils and the various bits and bobs needed. Basically taking scrap and building a shop. If you do differential hardening, your fancy precision controlled furnace isn't going to be much good. The Master's test for a blade is to be able to put it in a vise and bend it 90 degrees without it either breaking or taking a set. He shows how to do that. Stan |

RogerN Forget the D2 for a while. It requires 1900 deg for hardening. That is 400 deg higher than O1. It also has a machinability of only 65 and grinding it is even tougher. Besides, stainless is overrated. That is why there is oil. Cobble together a decent beltgrinder and start with sheath knives in O1. When you get that running smooth, try some folders. Paul K.

Raid® to a cockroach. Sheriff Brody to a shark Bush to a Liberal The truth doesn't just hurt. It's painful, like a red hot poker shoved up their ass.

I will need to test it first and it is subject to verification. i |

It is harder to sharpen than most, but can be finished to a high-polish shine. http://www.allaboutpocketknives.com/...lade_steel.php D2 This material is a very high carbon steel (1.5%) that has superb edge holding ability and unmatched wear resistance, but lacks toughness. It is not as corrosion resistant as 440C or ATS-34, and is not considered a stainless steel because it only has 12% chrome. Stainless blades have 13% or more. One thing I noticed about knife making is that you can get a lot of money tied up in equipment, and I always like the idea of getting more equipment but not spending lots of dollars. I thought I could make a knife makers grinder by using tubing in the Reese hitch size ranges, maybe using polyurethane wheels ground true for contact wheels. I do not believe that there is any money to be made by knife making. I agree, I just want to make them for myself or maybe gifts, not for making money. The heat treating furnaces are quite high too. Maybe get some kiln firebrick and heat elements, fabricate a frame to hold the bricks, and use an industrial ramping temperature controller with a solid sate relay for temperature control. Then I can set it to soak, ramp to temperature, hold, then switch to tempering temperature. Also it seems one of the controllers would be great at annealing, heat, soak, let it cool at specified rate at the critical temperatures. Anyone here do any knife making? I do not and do not plan to. Seems like everyone wants to be making knives. But the equipment, you can get on the cheap. i I don't guess you have any small, shippable, heat treating kilns/furnaces? RogerN Maybe have a look in your area for 2nd hand ceramic kilns as they make a good heat treatment furnace in my experience. I have a small Gallenkamp heat treatment furnace which is used for small stuff and enamelling but doesn't currently have a PID controller. My main kiln is an 18" top loader that I use for normalising etc and I have a PID controller for that and it works well. The elements are a bit tired so it'll only just get to 1200C on a good day, not the 1300C it would originally do, but that is normally only needed for firing refractory castable items to working temps not heat treatment so it's fine. |

RogerN I have one small one, but it will have to go by freight. Freight cost to BUSINESS in your area, with forklift, that takes a semi truck, is $100. $100 more to a house. I will need to test it first and it is subject to verification. i While on the subject of freight cost, do you know what your freight costs would be to get something like that to the Central Freight terminal in Sherman, TX? I know residential is always big $, but I've got that freight terminal nearby where I could pickup from. And yes, I'm interested in a heat treat oven as well, especially now that I have a surface grinder. $150 to terminal. $100 more to a house. i Good to know, so if you find a good heat treat oven, small CNC lathe, etc. that I need it won't necessarily be too expensive to ship. Just keep in mind that the ovens are filled with a very fragile firebrick or compound..and the heating wires are very fragile once its been used a couple times. So they CANNOT be banged around much.

It's very difficult to keep them from burning because they're probably tempered at around 350 deg. F at the factory. -- Ed Huntress |
