Dan Breen Posted May 24, 2017 Share Posted May 24, 2017 Hi I have just quenched my blade and I need to temper it but all the methods I seem to find are to whack it in 300 C heat for a couple hours. I am just wondering if there is another way because that uses a bunch of propane. I have heard about watching the colour of the steel and the spine turning blue and the blade turning into a wheat colour. Just wondering about suggestions and also if the colour method works do I have to heat the metal up for a couple hours still thanks. Link to comment Share on other sites More sharing options...
Caleb Harris Posted May 24, 2017 Share Posted May 24, 2017 Most folks use a toaster oven set at 350-450 F, depending the steel. The torch method (watching the colors) is to use a torch to heat up the spine and watch the colors. It's pretty unreliable however and not very precise. 300 C is awfully hot, most steels require temperatures between 180 and 230 Celsius. Trying to make each knife just a little better than the last Link to comment Share on other sites More sharing options...
Dan Breen Posted May 24, 2017 Author Share Posted May 24, 2017 Oh ok thanks man so does a toaster oven still use a lot of propane or is it fairly propane efficient Link to comment Share on other sites More sharing options...
Bob Hewitt Posted May 24, 2017 Share Posted May 24, 2017 The toaster oven I use is electric, very cheap, and seems to work well! The temperature indicated on the controls is wildly inaccurate, but you can fit a "K" type thermocouple to measure the temperature accurately for not much money! bob Link to comment Share on other sites More sharing options...

Dan Breen Posted May 24, 2017 Author Share Posted May 24, 2017 Finally one last thing how would I heat treat something that would not fit in a toaster oven but the knife I am making now obviously does but say if I were to make a machete Link to comment Share on other sites More sharing options...
