bigman Posted February 5, 2018 Report Share Posted February 5, 2018 If you fancy a visit from the tink fairy then waters good , o1 is a oil hardening steel the o is for oil the warmer the oil the faster the quench will be, I aim for 75degrees Quote Link to comment Share on other sites More sharing options...

Walker570 Posted February 5, 2018 Report Share Posted February 5, 2018 I am certainly no expert at this game. I follow a system very similar which I saw on you tube many moons ago. I follow that rule as above, but don't pre warm the veg oil, I will next time and I put the blade in the oven as described. I just roll about an inch of the cutting edge back and forth in the oil which I believe leaves the spine/handle still flexible and less likely to break, although these are knives not crowbars. I have two commercially made knives which are un believably hard and having used them for some time they needed sharpening, what a game that was and had to resort to the wet wheel to get an edge back. I do believe that blades can be just too hard. Quote Link to comment Share on other sites More sharing options...

I understood this as normalising, cooling down on its own. Putting all the structure back to where it should be.

rovercoupe Posted February 5, 2018 Report Share Posted February 5, 2018 Only ever used dirty old mineral oil for o1 steel and never had a issue but only ever made a few blades. Blummin hard and sharp though! Quote Link to comment Share on other sites More sharing options...
ditchman Posted February 6, 2018 Author Report Share Posted February 6, 2018 well me being stupid...i visited this american site again..!!...........every time i ask a question on there...i get such a complicated answer...stuff about what is happening at the atomic level and graphs etc...never an answer to my question........... sooo i thought i would make it more interesting ...i added 15 pictures of what i was doing ...the strip down of the linisher etc...just so i could make the connection between...the tool steel and the knife bit making of. then i went back about 4 hours later............and alll the photos had been deleted...and some more totally incomprehensible rubbish ....it was like being in some NASA lecture theatre on a lecture about alien metals and uses from the planet Zog............ soo i had another look around on some of the other related topics.......every single section was virtually devoid of pics...but full of what looked like textbook answers............ and the conclusion i have come to is....they are the biggest Walter Mitty Bullpoopers on the planet................so i have been going to sales websites of knife makers and the answers im getting there are factual....believable....and practical to follow.......... if i would have followed the advice on the other USA bladesmithing forum....i would need $20.000 dollars of equipment just for heat treating alone........ god what a bunch of muppets eh Quote Link to comment Share on other sites More sharing options...

No need to quench when tempering in an oven, as removing it from the oven will drop the tempter quickly and stop the tempering process, you can then use water to cool it for handling, but if you wish to put it straight into the water from the oven I would use warm water, but the question is why use water?
