  1. It was a pretty old piece of steel. After I hardened/tempered it, I beat it up pretty good on a hard piece of oak. It chopped pretty well. The edge held up really well. Sometimes it's better to be lucky than good.
  2. I agree. Like you, I'm not in love with the result. It does feel surprising good in the hand. It is more triangular that shows up in this picture (fat and flat on top and thinner on the bottom). I meant for the middle section to to be deeper (from top to bottom) in order to get a kind of recurve toward the base, but I fcked that up somehow. Lots of lessons learned on this one. It started out life as a farriers rasp.
  3. My first attempt at a hidden tang knife. Many challenges. Many things learned.
  4. The primary purpose of a check valve is to prevent a reversal of flow. It seems like what you want is a self actuated pressure control valve. This kind of valve should close in the event of a sudden loss of downstream pressure.
  5. Is there a preferred method to remove rust from files? I bought some files in an estate sale. A few of them are rusty. I would like to clean them up but do not want to do any damage. to them. My first thought was vinegar, but I am open to other methods.
  6. If the oil is a little warmer at quench does the steel not harden as much??
  7. I made a knife from a small file to use as a paring knife. I finished it to near mirror finish. It wasn't perfect but pretty good. I used it to cut the peel off a grape fruit and the acid seesm to have etched the blade. Is there anything I can put on the blade to protect the finish??
  8. I spoke with a man from BOGGS TOOL COMPANY today. What a cool company. I was concerned about how much it might cost to have them fix up this old file. He quoted me a price that was some number (I don't recall) of cents per inch. So it' going to cost less than $4 to sharpen up this file. What a very cool company. The man added that if they can't sharpen in to meet their standards they will only charge me 25 cents. Amazing! Now all I have to do is find a container that the file will fit in. Thanks for the recommendation!!
  9. C Craft, I touched it up with a wire brush. It appears to say DISSTON USA BITE-RT
  10. I agree. I'm going to try to clean it up and make it useful.
  11. Just a random question. How big are the biggest files?? I make my knives from old files (like most beginners). So, I have been acquiring files at garage sales and estate sales. Today I bought a file, that for me, is gigantic. With the tang it is almost 2 feet long. It's bigger than a farriers rasp. I almost feel bad about the idea of grinding or cutting it.
  12. It's not easy to find! That is true. Just found some. I want to pair it with a birdseye maple.
  13. IF I use 3 one quarter inch copper pins in a knife handle, will that be durable?? Is copper round stock strong/durable enough to use in knife making? I really do not see copper used. This is why I ask.
