CrookedPath Posted June 4, 2015 Share Posted June 4, 2015 (edited) I just learned about this guy through this article. Pretty neat. Anyone ever try to recreate this? https://clarksonhistory.wordpress.com/2013/05/06/secrets-of-the-dead-the-richtig-knife/ Edited June 4, 2015 by Steve Sells Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 4, 2015 Share Posted June 4, 2015 Have you looked over the testing requirements for the ABS levels? Link to comment Share on other sites More sharing options...
MrMaelstrom Posted June 4, 2015 Share Posted June 4, 2015 That's immediately what came to mind, Thomas. I remember looking at those tests when I first started out and thinking that they were impossible/required some sort of dark ritual to pass. Then came more experience and a material science degree. So much cooler knowing why things work, in my opinion, and reading about reverse engineering artifacts from history also tickles my fancy. Link to comment Share on other sites More sharing options...
Crazy Ivan Posted June 4, 2015 Share Posted June 4, 2015 That's really interesting that he make have used molten lead as a quenchant. Something I never heard of before. Definitely not something I plan on experimenting with for obvious reasons. Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 4, 2015 Share Posted June 4, 2015 The one that really scares me is using mercury for a quenchant. Molten lead is fairly polite to work with at the temps for Austempering it doesn't push a lot of vapor till it gets closer to it's boiling temperature. I'm not a big fan of taking secrets to the grave and try to teach anything I know to lots of folks. Link to comment Share on other sites More sharing options...
CrookedPath Posted June 5, 2015 Author Share Posted June 5, 2015 I've been able to pass a few of the ABS knife function tests, not the bending in half part. I'll be making another test knife in the next month or so, so we'll see. I'll wait till I can pass those tests before tackling iron bars. Link to comment Share on other sites More sharing options...
kayakersteve Posted June 5, 2015 Share Posted June 5, 2015 Very cool article - I love visiting with the older generation. The level of knowledge this man took to the grave saddens me. Link to comment Share on other sites More sharing options...
HWooldridge Posted June 5, 2015 Share Posted June 5, 2015 As a general statement with regard to "secrets" - one must always consider the available technology at the time. In other words, it would be very difficult (practically impossible) for someone to have performed a cryo treatment if they lived in a time where super cooling compounds were not readily available, even in a lab. On the other hand, the ability to melt lead has been around for thousands of years so it's an instinctive thought for a blacksmith to temper a knife in that manner.

bikecopXXX Posted July 1, 2015 Share Posted July 1, 2015 The article talked about how many of his knives had cast aluminum handles. Wonder if he quenched in molten aluminum? Depending on the alloy it can melt at just a little higher temp than lead, and it conducts heat way better Link to comment Share on other sites More sharing options...

SLAG Posted September 30, 2016 Share Posted September 30, 2016 This article got me to thinking. I remembered an old martial arts display stunt that had a practitioner drive a samurai sword, (a.k.a. katana), through a substantial and very hard & thick material. I do not remember what it consisted of but it was impressive. Then the fellow sliced a piece of fabric floating in the air. There was a trick involved. The end of the sword was very sharp and that part cleaved the fabric. (probably thin silk). But the rest of the sword was not sharp at all. the sword and edge was robust enough to cut the hard material. Which may have been chain link iron. I wonder if anyone inspected the sword's edge to check its consistency. I am not suggesting that the fellow was pranking the audience. But there is a remote possibility that that might have been the case. It would go some way to explaining why the smith, cum knife maker, took his "steel treating secret" to the grave. SLAG.

JHCC Posted October 1, 2016 Share Posted October 1, 2016 SLAG, your story reminds me of something I learned from my old Tai Chi teacher. We were discussing sword forms, and he showed me an antique Chinese sword from his collection. The blade had different cross sections for each third of its length: the first, closest to the hilt, was extremely blunt -- almost rectangular cross-section -- and used primarily for blocking and parrying. The middle section had a very robust edge and was intended for heavy slashing, being the area around the center of percussion. The outer third was very slender and sharp, for thrusting and slashing at a distance ( as he liked to say, every drop of blood you lose ages you a year).

SLAG Posted October 1, 2016 Share Posted October 1, 2016 Mr. Hammer, Your Sifu, (a.k.a. Sensai) was a wise man. Medieval beheading swords are surprisingly blunt. Sharp ones would not work very well. SLAG. Link to comment Share on other sites More sharing options...
